This is my covenant which ye shall keep, between me and you and thy seed after thee -- that every male among you be circumcised.
God speaks this word to a man of ninety‑nine who had already tried to get a son his own way. The command sounds strange today — a mark cut into the body of every male in the household — so what is it for, and what does it mean now?
The timing matters, and so does what came just before it.
The first mention of circumcision in the Bible is in Genesis 17:10-14. God was silent for thirteen years. Then He breaks in and makes a covenant with Abram, when His servant is ninety-nine years old. Thirteen years earlier Abram had listened to Sarai his wife, and they tried to have a child through Hagar the slave woman. That led to the birth of Ishmael, with all the disaster that followed. It was offspring according to the flesh, not according to promise.
Earlier, God's sign to Abraham lay in dead animals. Now the sign is cut into the man himself.
Abraham no longer asks for a sign to show him that he will inherit the land. Not a word of the kind is said. Instead God speaks of the seal of circumcision. It is not now something outside him, as we saw in the dead animals of chapter 15, but "every male among you shall be circumcised." What does it mean? Flesh put to death before God, the sentence of death placed on man in His sight — in Abram's own person and in his offspring after him. Circumcision here is not introduced in a legal way. It is really the answer in man to the grace of God. Every child of Abraham takes the place of death by this sign, which pictures our death with Christ.
The sign came after faith, not before it.
Circumcision was the mark of being a Jew, the sign of God's covenant with His earthly people Israel (Gen. 17:10). But when was Abraham counted righteous? Before he was circumcised at all. So righteousness by faith was never limited to Israel alone. It is for all who believe, though they are not circumcised. To a Jew who gloried in circumcision as the distinguishing mark of God's people, this argument is unanswerable: when Abraham was counted righteous, he was uncircumcised.
The words "every male among you" swept in the whole household, whatever a man's origin.
The covenant of circumcision is now introduced. Every member of the household of faith must bear in his body the seal of that covenant. There must be no exception. "Both he who is born in your house and he who is bought with your money shall surely be circumcised. So shall My covenant be in your flesh an everlasting covenant."
The penalty for refusing it was severe.
If an Israelite was not circumcised he was to be cut off from his own nation. Why? Because he had broken God's covenant. He had no part in the blessing God had promised. God's promise is not given to man as alive in the flesh, but to those in whom the flesh stands under the sentence of death. The sign of circumcision was necessary for Israel. Today we should learn the spiritual reality of it, as seen in Philippians 3:3. Yet even in Christianity the outward sign of baptism has its serious place.
The appointed day carries its own weight.
It becomes clear that circumcision means the flesh must be kept in the place of death. The flesh can add nothing to the doing of God's will. "He who is eight days old" was to be circumcised, and the eighth day points to a completely new start. Only a new life within can produce anything for the pleasure of God.
Christians are not asked to keep the rite. What it stood for still holds.
If God covenants to bless by His Almighty power, then on our side there must be no confidence in the flesh and no allowance of its activity. For the believer today, circumcision is "of the heart, by the Spirit, not by the letter. His praise is not from man but from God" (Rom. 2:29). Refusing the flesh is not merely an outward neglect of the body that the world can see. It means refusing the flesh in all its inward workings in the heart — its self-confidence, self-righteousness, vanity and lusts — as something the cross has condemned (Col. 2:11).
- Flesh fails. Ishmael came from human arrangement. God waits thirteen years, then speaks when Abraham is ninety-nine and man can produce nothing.
- Flesh sentenced. The sign is no longer outside Abraham but cut into his own body — the sentence of death on man in God's sight.
- Flesh not trusted. Abraham was counted righteous before he was circumcised. The sign sealed a righteousness faith already had, and that blessing reaches people without the mark.
- Flesh universal. No one in the household was exempt, born there or bought. To refuse the sign was to break the covenant and be cut off.
- Flesh replaced. The eighth day points to a completely new start. For believers the reality is inward: refusing self-confidence and self-righteousness, which the cross has condemned.
And ye shall circumcise the flesh of your foreskin; and [that] shall be a sign of the covenant between me and you.
God gives this command to Abraham after a long wait, when his own attempt to secure the promised family had already failed. The mark is not a price for the promise but the sign of an agreement God had already made — so why did God set that sign in the flesh?
God did not negotiate this agreement. One reference work sets it beside God's promise to Noah, where the rainbow was the token:
The covenants made by God are of a different order. He makes His covenants from Himself, without consulting man. With Noah God made a covenant that He would not again destroy the world by a flood. As a token of that covenant, He set the rainbow in the cloud (Gen. 9:8-17). A covenant like this takes the form of an unconditional promise. Such was God's covenant with Abraham... He also gave him the covenant of circumcision (Gen. 17:10-14; Acts 7:8).
The law of Moses later took up this rite, so it is easy to read it as pure law-keeping. One commentator answers that:
No one should think circumcision must be a legal thing. In the setting it is put in here it goes together with grace — the sign that the flesh is put to death. The law did take it up when that system was later imposed. But in itself, as our Lord Himself shows, it was not of Moses, but of the fathers... It means flesh judged, and that is the true spiritual meaning of what God then instituted.
So why a mark in the body, and not another sign in the sky? The mark speaks about the flesh it is cut into:
What does the sign mean? Clearly, it is a symbolic witness that faith, not flesh, is the principle of relationship with God. In giving Abraham circumcision, God says, "You must carry in your body the sign that your flesh is profitless. You must have in yourself the sign that the sentence of judgment is on the flesh. You must accept a mark that means this: faith is the principle on which you are in relationship with Me."
The command came when Abraham had nothing left to give. The long wait was part of the lesson:
The flesh had already failed him, yet he later took the slave woman to himself, and had a child who was only the "wild man," not the child of promise. Nature was still strong in Abraham, so God went on for fourteen years as if the promise slept in His own mind — unfulfilled. But "when he was about a hundred years old," and Abraham's body "was now dead," God could come in again... "I am the Almighty God, walk before Me, and be perfect." For a dead Abraham an Almighty God alone would do, for Abraham could not help God to raise the dead. There He gives him the covenant of circumcision.
Circumcision did not make Abraham righteous. It stamped what was already true:
Romans 4 teaches that circumcision was "a seal of the righteousness of faith." "Abraham believed God, and it was counted to him for righteousness." God counted him righteous, and then set His "seal" upon him.
The sign also marked out a people. It showed that Israel belonged to God:
Circumcision is a sign in God's people that they are indeed His, set apart to Himself according to His purpose. To the father of the faithful it was a token of the covenant God had made with him (Gen. 17:11)... It showed that God had set Israel apart to Himself from the nations around them.
How much did Abraham understand? Commentators differ. One writer holds that the full meaning waited for Christ:
As far as Abraham was concerned, circumcision was just a rite to keep. Nothing shows that anyone taught him its spiritual meaning... It looks as if its full meaning did not come to light until "the circumcision of Christ" (Col. 2:11) had actually taken place.
The reality the sign pointed to is a cutting off that no surgeon performs:
Circumcision was God's token of the covenant with the Jews, and of the putting off of the flesh, which was required to be part of God's people. It had its reality in Him... This is the true circumcision of Christ made without hands. Circumcision made by hands was only the sign of this putting off of the body of the flesh.
- Covenant — God made this agreement alone, without consulting Abraham. The sign in the flesh points to a promise, not a bargain.
- Sign — the mark says the flesh is profitless and under sentence. Faith, not flesh, is the basis of relationship with God.
- Timing — God gave it when Abraham's body was as good as dead, so the Almighty alone would keep the promise.
- Seal — faith came first. Circumcision only stamped God's seal on a righteousness Abraham already had.
- Reality — the outward rite pointed to "the circumcision of Christ": a putting off of the flesh made without hands.
And at eight days old shall every male in your generations be circumcised among you -- he who is born in the house, and he who is bought with money, any stranger who is not of thy seed.
The command falls on a baby eight days old. It also reaches past family lines to every male in the household, whether born there or bought from a foreigner. Why mark a child too young to understand it? And why mark people outside Abraham's own family?
God speaks after a long gap. Abraham had already tried to secure a son his own way:
The first mention of circumcision in the Bible is in Genesis 17:10-14. After a silence of thirteen years God breaks in and makes a covenant with Abram when His servant is ninety-nine years old. Thirteen years earlier Abram had listened to Sarai his wife, and tried to produce a seed through Hagar the slave. This action resulted in the birth of Ishmael with all its later disaster. It was a seed according to the flesh, not according to promise.
The rite was not attached to Ishmael's birth but to the son yet to come.
Circumcision was instituted, not when Ishmael was born, but in view of Isaac, the seal of the covenant. The principle was God's righteousness. Man was judged as evil and the flesh put to death.
Circumcision cuts away flesh. Commentators read that cut as God's verdict on human nature:
Circumcision means that the flesh must be kept in the place of death. The flesh can contribute nothing towards carrying out the will of God. Only a new life within can produce anything for the pleasure of God.
The same logic explains what happened to an Israelite who refused the sign:
If an Israelite was not circumcised, he was to be cut off from his own nation. Why? Because he had broken God's covenant. He had no part in the blessing God had promised. God does not give His promise to man as alive in the flesh. He gives it to those in whom the flesh is judged as under sentence of death.
The number is not arbitrary. Seven days close a week; the eighth opens a new one.
EIGHT. A new start outside of, but connected with, the order of creation: so, in resurrection. Circumcision was on the eighth day, the start of a new fellowship. Eight people were saved in the ark, to begin a new world.
For the child, the day points forward to what he will inherit:
"Eight days old" shows what a fair inheritance we are destined for. The eighth day speaks to us of new creation, now that the first week of the old one has run out. Only the power of that knowledge can keep practical circumcision going.
A baby of eight days understands nothing of what is done to him. That does not weaken the sign:
Circumcision took place as early as eight days old. At that age the child could not understand anything about it. Its meaning stays the same whether people understand it or not. The same is true of baptism, which also teaches death to the flesh.
The verse names two groups beyond Abraham's own children. Their numbers were large:
Abraham had 318 servants born in his house. Jacob had a still larger number. And they had been received into the covenant, though they were not natural descendants... There may have been thousands of such servants.
The sign was permanent. It even gave outsiders a seat at Israel's redemption meal:
The token of the covenant was to be in his flesh for an everlasting covenant, the sign of the lasting terms on which his descendants stood with God. How striking this is! Under the law the whole nation in the flesh had to carry the sign of circumcision. That sign was a seal of the righteousness Abraham had by faith while he was still uncircumcised. Yet at any time, though the dividing wall still stood, any Gentile could freely take up the sign of that same righteousness. With his males circumcised, he could sit down to the Passover, the feast of redemption!
The outward mark was never meant to stand alone. In Israel it soon did:
The nation began to carry this out very carefully, but its true meaning was soon lost. It became just an outward rite with very little inward reality. It had no effect at all on how people lived. God never intended an outward rite to be kept without inward reality. That gives Him no pleasure.
- Covenant — the sign came after thirteen silent years. It pointed forward to Isaac, not back to Ishmael. It belongs to promise, not to human arrangement.
- Cutting — the cut marks the flesh as judged, under sentence of death. God's promise rests on nothing a person can produce.
- Eighth day — the day after the week ends stands for a new start and resurrection. The baby carries the mark of an inheritance long before he can understand it.
- Household — servants born in the house or bought with money entered the covenant too, though they were not natural descendants. Even a Gentile could take the sign and eat the Passover.
- Reality — a rite kept without inward truth gives God no pleasure. The mark was always meant to show in the way a person lives.
He who is born in thy house, and he who is bought with thy money, must be circumcised; and my covenant shall be in your flesh for an everlasting covenant.
Genesis 17 is full of God's promises: again and again He says "I will." Then comes a sign in the flesh, and verse 13 puts it on every male in Abraham's house — sons and servants alike.
Abraham is ninety-nine here. One writer weighs what Abraham can still do at that age, and how often God says "I will" in this chapter.
The faith of Abram was tested further at this point. If his patience gave way at 86 years old, what now? He is now 99 years old. The whole matter has become impossible as far as man and the flesh are concerned. The power of God must come in if the promise is to be fulfilled. Yet notice how many times "I will" appears in Genesis 17. This is the statement of an unconditional covenant. All of it rests on God's unchangeable will and purpose.
The verse says the covenant will be "in your flesh." One writer explains what a mark in the flesh gives up.
Circumcision was the sign of this very covenant (see Gen. 17). It expressed the giving up of all confidence in the flesh. That giving up leaves a person to know, with a dead Abraham, the power of the Almighty. God insists that the token of the covenant must be in the flesh of all His people.
Later generations turned the mark into a matter of pride, which is the reverse of its meaning.
It is a sign that the flesh can have no recognition with God, and that the sentence of death must be passed on it. Faith in this way confessed that the flesh is utterly worthless, and took advantage of what God's grace provided… It is a solemn thing that such an ordinance should become a mere matter of boasting in the flesh. But that is what happened in Israel. The flesh boasted and took pride in the distinction. If they had understood its meaning, they would have seen that through it God was pouring contempt on the flesh and all its efforts.
Who counted as Abraham's household? One writer draws the line, and marks the first time Scripture ties a household to its head.
The sign was circumcision, and Abraham, his descendants and all his household were to keep it. That last term takes in everyone born in his house, and the slaves he bought. A servant who was only hired for a time was clearly left out. Here for the first time in Scripture we find a household recognised as identified with the man who is its head.
No one inside that circle could opt out.
The covenant of circumcision is now introduced. Every member of the household of faith must carry in his body the seal of that covenant. There must be no exception.
The mark did not create Abraham's standing with God; it stamped a standing he already had.
But what does the sign mean? Plainly, it is a symbolic witness that faith, not flesh, is the principle of relationship with God. In giving Abraham circumcision God says, "You must carry in your body the sign that your flesh is worthless. You must have in yourself the sign that the sentence of judgment is on the flesh. You must accept a mark which means that faith is the principle on which you stand in relationship with Me." But if circumcision is the sign of a covenant of grace, of relationship with God on the principle of faith, then it is a seal on the righteousness of faith. That righteousness was already Abraham's before he was circumcised.
The word "everlasting" reached the whole generation of Israel. One writer says what has since taken its place.
Circumcision is a sign in God's people that they truly belong to Him, set apart to Himself according to His purpose. To the father of the faithful it was a token of the covenant God had made with him (Gen. 17:11). The Lord's words, "So shall my covenant be in your flesh an everlasting covenant" (v. 13), took in the whole generation of His people of old. Circumcision showed that Israel were separated to Himself from the nations around them. The Christian is separated to God in Christ, who is risen from the dead and who lives in heaven, not on earth. The circumcision made without hands, the circumcision "of the heart, by the Spirit, not by the letter" (Rom. 2:29), has now taken the place of the outward rite.
- Source. The covenant runs on God's repeated "I will." At ninety-nine, Abraham could add nothing to it.
- Sign. God set the token in the flesh, because the flesh lies under a sentence of death and can claim no recognition from Him.
- Seal. The mark sealed a righteousness Abraham already had by faith. It never produced the blessing; it certified it.
- Scope. Born in the house or bought with money, the whole household stands with its head, and no male is left out.
- Succession. The outward rite has given way to the circumcision made without hands — a matter of the heart, by the Spirit.
And the uncircumcised male who hath not been circumcised in the flesh of his foreskin, that soul shall be cut off from his peoples he hath broken my covenant.
God has just given Abraham circumcision as the sign of the covenant, and here He sets a penalty for refusing it. Why should a mark in the body carry so much weight?
The verse does not say the uncircumcised man is careless; it says he has broken the covenant. One writer explains the loss in terms of what the sign stood for.
If an Israelite was not circumcised he was to be cut off from his own nation. Why? Because he had broken God's covenant. He had no part in the blessing God had promised. God does not give His promise to man as alive in the flesh. He gives it to those in whom the flesh is judged and under sentence of death.
The mark did not buy Abraham's standing with God. It stamped what God had already reckoned to him.
The covenant of circumcision is now introduced. Every member of the household of faith must bear in his body the seal of that covenant. There must be no exception... Romans 4 teaches us that circumcision was a seal of the righteousness of faith. "Abraham believed God, and it was counted to him as righteousness." God counted him righteous, and then He set His seal on him.
Refusing the mark was refusing a message. The message was about the worth of human nature before God.
But what does the sign signify? Plainly, it is a symbolic witness that faith, not flesh, is the principle of relationship with God. In giving Abraham circumcision God says, "You must carry in your body the sign that your flesh is worth nothing. You must have in yourself the sign that the sentence of judgment is on the flesh. You must accept a mark that says faith is the principle of your relationship with Me."
Commentators differ on what being cut off meant in practice. L. M. Grant speaks of losing a place in the nation; F. B. Hole reads it as death — a penalty that later caught up with Moses himself.
God was acting for Israel under the covenant He had made with Abraham, recorded in Genesis 17:1-14. Circumcision was the token or sign of that covenant. God said plainly that the penalty for ignoring circumcision was death. Moses was chosen to be the chief actor in Israel's deliverance under that covenant — and he had not obeyed the sign! As the responsible person he was subject to the death penalty!
The wilderness years show how far the neglect went, and what it cost Israel in worship.
Nothing was more basic to this covenant than the ordinance of circumcision. The uncircumcised boy was to be cut off from his people (Gen. 17:14), and no such person could eat the passover at all (Ex. 12:48). So either Israel ignored these laws, or they almost entirely dropped the passover toward the end of the wilderness journey. By then no one under forty could have been circumcised at all... How the patience of the Lord with the people is evident!
Israel kept the ceremony and lost the point. The same danger meets anyone who values a religious practice for its own sake.
God set up circumcision with the covenant He made with the fathers, as we read in Genesis 17. The law confirmed it later. The constant tendency was to keep the outward ceremony and overlook its meaning. Israel was to be a people completely cut off for and to God. A circumcised heart would have cut off self-love, as they came to know the love of God.
The demand behind the sign has not changed, though the sign itself has given way to the reality.
If God makes a covenant to bless by His Almighty power, then on our side there must be no confidence in the flesh and no allowance of its activity... Refusing the flesh is not just an outward neglect of the body that the world can notice. It is the refusal of the flesh in all its inward workings in the heart — its self-confidence, self-righteousness, vanity and lusts — as that which has been condemned in the cross (Col. 2:11).
- Sentence. The mark said the flesh is under sentence of death; to refuse it was to claim a place with God on the ground of nature.
- Seal. God counted Abraham righteous first, then sealed him. The sign confirmed that righteousness; it never produced it.
- Scope. Every member of the household bore the seal, with no exception.
- Seriousness. The penalty threatened Moses himself, and it silenced Israel's Passover through the wilderness years.
- Substance. The lasting danger is keeping the form and losing the meaning. God looks for the flesh refused in the heart, not just marked in the body.
