What made some animals clean and others unclean (Genesis 7)?

v.1The first verse of Genesis 7 furnishes us with the first instance of how God, in dealing with men on the earth, links a man's house with himself — "thou and all thy house" occurs for the first time. Salvation from judgment poured out on earth is before us here, but in Acts 16:31 the same principle holds good in regard to eternal salvation. How thankful we should be for that word!

v.1Certainly so tremendous a project as the preparing of the ark would attract great attention by all the people, for in spite of Noah's preaching of righteousness (2 Peter 2:5), none were persuaded that God would judge the world by a flood. They likely considered him mentally affected and became “scoffers walking after their own lusts” (2 Peter 3:3-7). When the time came, God instructed Noah to enter the ark with all his household, not because his household is said to be righteous, but because God had seen Noah to be righteous, the only one in his generation. At least he had enough influence in his own family that they would willingly enter the ark also. Yet they were included on the basis of his faith, a principle of real importance in God's dealings. He is concerned not only as to individuals, but as to households.

In Genesis 7 we have another order of facts. It opens thus: "And Jehovah said to Noah, Come thou and all thy house into the ark." Is this merely the conserving of the creature? Not so. It is the language of One who has special relationships with Noah and with his family. "Come thou into the ark," says He; "for thee have I seen righteous before me in this generation." "Righteous" — is this a question of creation as such? It is not, but rather of moral relationship. "For thee have I seen righteous before me in this generation. Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female. Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth." Certainly this is not mere creation in view, but special dealings of a moral sort. Almost every word gives evidence of it. "Of every clean beast thou shalt take to thee by sevens … and of beasts that are not clean by two." It is God providing not for the perpetuation of the creature merely, but with marked completeness for sacrifice. Consequently we have this perfect care over the maintenance of His rights and place as One that governed morally. "And Noah did according to all that Jehovah commanded."

v.1-16Had Noah any anxiety about the billows of divine judgement? None whatever. How could he? He knew that "all" had been poured forth, while he himself was raised, by those very outpoured billows, into a region of cloudless peace. He floated in peace on that very water by which "all flesh" was judged. He was put. beyond the reach of judgement; and put there, too, by God Himself. He might have said, in the triumphant language of Romans 8, "If God be for us, who can be against us?" He had been invited in by Jehovah Himself, as we read in Genesis 7:1, "Come thou and all thy house into the ark;" and when he had taken his place there, we read, "the Lord shut him in" Here assuredly, was full and perfect security for all within. Jehovah kept the door, and no one could go in or out without him. There was both a window and a door to the ark. The Lord secured, with His own omnipotent hand, the door, and left Noah the window from which he might look upward to the place from whence all the judgement had emanated, and see that no judgement remained for him. The saved family could only look upward, because the window was "above" (Gen. 6:16) They could not see the waters of judgement, nor the death and desolation which those waters had caused. God's salvation — the "gopher wood," stood between them and all these things. They had only to gaze upward into a cloudless heaven, the eternal dwelling-place of the One who had condemned the world, and saved them.

v.1-9Note the continued difference between God and Lord; God is a more secret, and at the same time universal name - Lord, of positive relationship. There is no question of sevens, or clean beasts with God, but with the Lord. God in speaking to Noah speaks of His own thoughts, and what is before Him; the Lord commands him in certain duties and relationships.

v.2-3Thus in relation to His place as creator God preserved two of every sort; in relation to His own moral government He would have seven taken into the ark — seven animals of each clean sort; of the unclean just enough would be there to preserve what He had made. It is evident therefore that in the one case we have that which was generally necessary, in the other case that which was special and due to the relationship in which man was placed with Jehovah. Thus it is seen at once that, instead of these wonderful communications being merely earlier and later legends put together by a still more modern editor, who tried to make something complete by stringing together what did not aptly fit, on the contrary, it is the Spirit of God who gives us various sides of the truth, each falling under the title and style suitable to God, according to that which was in hand. Put them out of their order, and all becomes confused; receive them as God has written them, and there is perfection in the measure in which you understand them.

As to the "two of every sort" in chapter 7, and "seven clean" in verses 2, 3, the first were male and female, to keep them alive; when they were clean beasts, he took fourteen. I have no doubt the "clean" were what were customarily given for sacrifices. Who would offer a ravenous wild beast in sacrifice to God, but sheep or oxen? This difference of a provision for the race and for sacrifice is bound up with the different use respectively of God (Elohim) and of the LORD (Jehovah).

If the reader turns to a paragraph Bible, he will find these statements in two separate paragraphs, the first extending from Genesis 6:13 to the end of the chapter, and in it God is commanding, and God is obeyed by Noah. Observe, it is God here. The other expression referred to begins with chapter 7, and ends with the fifth verse, and here it is Jehovah commanding, and it concludes with, "thus Noah did, according to all that Jehovah commanded him." The first allusion to "Two of every sort shall come unto thee [Noah] to keep them alive," is God's (Elohim's) care of His creatures to preserve every kind alive in the earth. But when we read of His taking "of every clean beast by sevens, his male and his female," it is God as Jehovah who speaks. And why? Because He is now arranging as in relationship with man for sacrifices ― types of Christ. The paragraph, therefore, begins with, "Jehovah said unto Noah, Come, thou and all thy house, into the ark; for thee have I seen righteous before me in this generation." (Chap. 7:1.) How striking this is! It is God as Jehovah owning relationship on the ground of redemption with Noah, the man of faith, as we know he was. (See Heb. 11:7.) We are therefore told, in the next place, that he was to take clean beasts, by sevens, and also the fowl of the heaven by sevens, and it is then added, "to keep seed alive upon the face of all the earth," for the judgment of the deluge was at hand. Now, the reason of this addition to the general command of two of every sort is very manifest to souls who have to do with Christ, as taught and led by His Holy Spirit. It was Jehovah's mind that the accomplished work of Jesus, on which all our blessings are founded, should be frequently before Him in figure by the offering up of sacrifices. For this "clean beasts," and "fowls of the heaven" were indispensable, for surely nothing unclean could typify the Holy Saviour. Had there been only "two of every sort," the offering of some in sacrifice would have put an end to those particular kinds of created beings. So the "sevens" left ample room both for sacrifices, and "to keep seed alive on the face of all the earth." Thus Jehovah, who counted His people "righteous" on the principle of faith in a coming Redeemer, shadowed forth Christ in the "clean beasts" and "fowls" for sacrifices, as Adam and Noah in their measure also were figures of Him, as "the last Adam," in having dominion over the created things around them. We find that, no sooner did Noah emerge from the ark, and set foot on the purged earth, than he "builded an altar unto Jehovah, and took of every clean beast, and of every clean fowl, and offered burnt-offerings on the altar," which most blessedly typified Christ's sacrifice of Himself. "And Jehovah smelled a sweet savour; and Jehovah said in His heart, I will not again curse the ground any more for man's sake," etc. Now, where is the "inaccuracy"? Is it not clear that the "sevens" were actually needed for the sacrifice of "burnt-offerings;" and, if not provided for, would have at once exterminated some, at least, of the "two of every sort"? Where is the "contradiction"? If two applied to all unclean animals, and seven to clean ones, because of the requirements of sacrifices, where is the difficulty? The child of God, to whom the scriptures are "profitable," and for whose "comfort" they are written, finds a real delight in the contemplation of such passages of holy scripture, as opened up to him by the Holy Spirit; while the philosopher, and all other of the wise and prudent of this world, see nothing to interest, and try to see much to find fault with. Now we trust it is clear to our readers, why it is said of Noah, that "Jehovah shut him in," while in the same verse it is said, they "went in male and female of all flesh, as God commanded him." (Gen. 7:16.) The scriptures abound with such marks of their divinity. How true are our Saviour's words to the Father, "Thou hast hid these things from the wise and prudent, and hast revealed them unto babes. Even so, Father, for so it seemed good in thy sight." (Matt. 11:25-26.)

The first time we read of clean and unclean animals is when Noah went into the ark: he was instructed to take seven pairs of each of the clean beasts and clean fowls and only two of the unclean; we have no instructions as to how Noah distinguished them, but it shows that in early days there was a distinction between the clean and unclean. Those called 'clean' were doubtless clean for sacrifice, and not for food, as nothing is said of man eating animal food till after the flood, and then "every moving thing" was given for food. When Noah came out of the ark he offered of every clean beast and every clean fowl for burnt offerings. Gen. 7:2; Gen. 8:20.

v.2-10God's instructions as to animals and birds are repeated in verses 2 and 3. Then a respite of seven days is given before the flood would come. This shows again the longsuffering of God. When men saw the large number of animals coming to the ark and then the family of Noah all entering this completed gigantic vessel, at least then they ought to have realized that this project was not merely conceived by Noah's imagination, in spite of the fact that rain had evidently never before fallen (Gen. 2:5-6). But God gave men another week to change their minds. Perhaps as those few days passed, people were becoming more confident each day that nothing was going to happen, rather than being sensibly concerned.

v.1-16If we read verses 1-16, we might be tempted to think that here was a good deal of repetition, but we believe the passage is so worded to impress us with two things: first, the exact and careful way in which Noah obeyed God's instructions; second, the exact ordering and timing of all God's actions in judgment; as also, that the great catastrophe was of a nature wholly transcending any ordinary convulsion of nature and altogether an act of God.

v.11-12The term, "windows of heaven," is very expressive. It denotes an outpouring from God above; it may be in blessing, as Malachi 3:10 shows, but here it was in judgment. The devastating waters descended for forty days and forty nights, a period that we meet again in the Scripture several times, indicating a full period of testing. But also there was from beneath a breaking up of the established order. What exactly is signified, when we read that, "the same day were all the fountains of the great deep broken up," it is impossible to say. The tremendous event had never happened before, and it will never happen again, for we read, "neither shall there any more be a flood to destroy the earth" (Genesis 9:11). So obviously we must be content to know that there were immense internal convulsions, that produced a mighty upsurge of earth's waters, to meet the waters descending from above.

v.11-12In verse 11 God gives the date of the beginning of the flood in relation to the age of Noah, not only the general time, but the exact day, the 17th day of the second month, in Noah's 600th year. The many dates, names and places recorded in scripture are an invitation to anyone to check as he pleases as to the accuracy of the word of God. In this verse we are told however that, not only were the windows of heaven opened, but first that the fountains of the great deep were broken up. This must have involved a tremendous tidal wave, the seas throwing up such waters as to cover the whole habitable earth. For it is claimed that the skies above us would be absolutely full to saturation point it they contained enough water to cover the earth to a depth of only thirty feet. One scientist has written that if a planet, — Saturn for instance, — were to come into close proximity to the earth, and make two passes around the earth, it could cause a tidal wave that would cover the whole earth, lasting 150 days. Of course, God could use such means as this if He pleased, or He could accomplish what He did apart from such means. But to add to the awesome inundation, the rain fell for forty days and forty nights (v. 12).

v.12-17As to the number "forty," it seems to me to have the sense of endurance in it. Forty stripes save one is thirty-nine; for they need a three-thonged rod, so that they could only give thirty-nine by the law, not to exceed forty. It is a length of duration and trial in that way, testing and patience and endurance. So Moses in his three periods of life. Again, Ezekiel lay forty days on his right side for Judah, as a sign, a day for a year, according to the years of Judah's iniquity (Ezek. 4). Jonah's proclamation was yet forty days and Nineveh shall be overthrown; though they did not yet come under the penalty, they were tried. Elijah had been forty days apart, as Israel of old in the wilderness forty years. Here it was till the ark floated.

v.13-16The last day came however, and each of the four men and four women took the last decisive step which ensured their preservation from destruction. The decisive step for each was when they planted one foot on the ark, and removed the other from the earth that was under judgment. It was impossible to have one foot in and one foot out. It was either both feet in, or both feet out. Which thing is a useful parable for Gospel preachers today. Their action endorsed God's judgment against the world, and expressed their faith in the Divinely appointed way of salvation. Once inside the ark, "the Lord shut him in." When the Lord shuts, no man can open — not even Noah himself had he wished to do so. The shut door secured salvation for the eight souls, and ensured destruction for the world of the ungodly.

v.16In our day the Gospel is too often preached as a way of escape from merited judgment, without any emphasis on the other side which is presented here. By building and entering the ark Noah "condemned the world" (Heb. 11:7), and the reception in faith of Christ as Saviour and Lord today involves just the same thing. Let us not shirk the issue, as though it could be Christ and the world. It must be one or the other; and may God help all who preach the Gospel to declare this with boldness.

v.13-16After all were in the ark (possibly by the end of the seven days' respite) God shut them in. It was not merely that Noah shut the door. Once God had shut the door, it could not be opened again to allow others in who might be so terrified when the rain began to fall that they would rush to seek refuge. It was too late when the door was closed. How solemn a lesson for those who neglect the salvation of their souls until too late!

v.16So we find what shows the folly of this yet more in what follows: "And they that went in went in male and female of all flesh, as God commanded him; and Jehovah shut him in." The two terms occur in the very same verse; yet is there not an evident propriety in each case? Unquestionably. They went in male and female. What is the idea? Moral relationship? Not at all. "Male and female" has to do in itself with the constitution of the creature, nothing whatever necessarily with moral relationship. In male and female God acts according to His rights and wisdom in creation; and consequently there it is said, "as Elohim commanded him." But when all this is done with, who was it that shut Noah in? "Jehovah." There we have delight in the man who had found grace in His eyes. No doubt the mere act could have been effected in other ways. Noah might have been enabled to shut himself in; but how much more blessed that Jehovah should do it! There was no fear then. Had it been merely said that Elohim shut him in, it would have simply suggested the Creator's care of every creature; but Jehovah's shutting him in points to special relationship, and the interest taken in that righteous man. What can be more beautiful in its season?

v.17-24The flood waters, which brought destruction upon the world of the ungodly, had the effect of lifting the ark "up above the earth." This may serve to remind us that the salvation of God has an elevating effect at all times. Today, very specially, we are called to set our mind "on things above, not on things on the earth" (Col. 3:2). When "the waters prevailed exceedingly upon the earth," no flesh was visible, and nothing but death was to be seen. God's word as to "the end of all flesh" coming before Him, was fulfilled, for now all were either covered in the waters of judgment, or in the ark, as it rode between the waters surging from beneath and descending from above. Noah and his family were out of sight in the ark a figure of the new place which is ours "in Christ Jesus," involving the non-recognition of our old status in the flesh.

v.17-24How thankful we should be that judgment fell, not upon us but upon our gracious Saviour, just as the death-waters fell, not upon Noah but upon the ark. The whole episode is likened to baptism in 1 Peter 3:21, or rather, baptism is likened to it. The first mention of Christian baptism being administered is in Acts 2, where it is connected with the word, "Save yourselves from this untoward generation." The passing through death in a figure, and thus cutting all links with old associations is, we believe, the main thought in baptism. All Noah's links with the old world were cut by the baptism of the flood. Peter wrote to converted Jews, who had been severed by baptism from the mass of their nation, and thus saved from the governmental judgments about to fall on it. For us Gentiles baptism has the same significance, severing us — if we understand it and are practically true to it — from the world which is rushing on to judgment. Are we true to what baptism means?

v.18It was wholly of God. He devised the ark, and furnished Noah with its specifications. The storm might rage, both above and around it, but the ark was never submerged. "The ark went upon the face of the waters" (Gen. 7:9). Type of Him who bore the storm of divine wrath on behalf of all His people. The greatness of His person gave Him competency for so mighty a work.

v.19-24Its dimensions were such that "all the high hills, that were under the whole heaven were covered." This seems to indicate that it was universal, and it is certain that nothing of a local nature could possibly have lasted for so long. Moreover the breaking up of "the fountains of the great deep" very possibly involved great changes on the surface of the earth: in other words, the configuration of continents, mountains, seas, etc., may have been very different in the antediluvian age from their present form.

v.19-20I believe the flood was all over the earth, wherever man was. There is no mistake. People have called the universality in question, using general terms, as if it only covered the inhabited earth. But scripture says, "the mountains were covered," "and the tops of the mountains were seen," and so on; this looks like universality. You must let in a miracle in any case: and so it is all one after all. Suppose Mount Ararat, fifteen or sixteen thousand feet high, in northern Armenia, was covered; well, if the waters were not all round, and away too, they would have run off, and covered somewhere else; there must have been a miracle anyhow. The universality of the flood, absolute universality, seems to me to be positively meant and intended, because of destroying the world that then was. God puts an end to the whole system of the world. It was as complete a judgment of the earth and all that was on it, on the part of God, as it will be presently by fire. Everything in the whole order and system of the world that had life perished, "the earth standing out of the water and in the water, whereby the world that then was, being overflowed with water, perished": so Peter tells us, and anything that enfeebled it I should not admit: all mere physical things are consequent upon it. Either reject the word of God, or else Mount Ararat was covered. As to universal destruction, everything in the world was put an end to. The world that then was is distinct from the world that now is; and this is of immense moral import to us. God says He will never do it again, but the next time it will be by fire.

v.19-23The duration of the flood and its eventually covering even the high mountains, insured that all human and animal life would be destroyed. Of course this did not affect the life in the seas. It is reported that there are some high hills in the mid-east almost covered with human and animal bones, perhaps the result of people and animals trying to reach the highest elevation they possibly could for safety, but all in vain.

v.21In verse 21 and the like, we have the witness of the way in which the corporate nature of man - the ha-Adam is spoken of, so in chapter 6:1. o protor anthropos.

v.24Of course the ark floated on the waters, and all inside were preserved. The ark itself is typical of the Lord Jesus, the one safe refuge from judgment for every child of Adam who will receive Christ as Savior. Evidently including the forty days of rain, the waters prevailed on the earth for 150 days (cf. v. 11 and Gen. 8:4).

As to the flood itself, the account given (Genesis 7:11 — Genesis 8:14) is quite explicit, both as to its duration and its dimensions. The tremendous rain lasted for 40 days and 40 nights. The waters prevailed from the 17th day of the 2nd month to the 17th day of the 7th month, when the ark grounded on the mountains of Ararat. On the 1st day of the 10th month the tops of the mountains were seen. On the 1st day of the 1st month of a new year the waters had vanished from the face of the earth. On the 27th day of the 2nd month the earth was sufficiently dry for the occupants of the ark to go forth from it — one year and 10 days having elapsed from the onset.

85 Tisri was the first month, that is, part of September and October. The fourteenth day of Abib was the end of March, as Abib began in the middle of our March, and went on to the middle of our April. It was five months that the waters prevailed; and after the end of the 150 days the waters abated, and the ark rested on the mountains of Ararat, the waters being two months and a half in running off.
