I set my bow in the clouds, and it shall be for a sign of the covenant between me and the earth.
The flood is over, and God gives a promise, not a warning — tied to something Noah could see in the sky whenever rain returned. Three questions follow: what did God "set" there, who is the sign for, and how far does the covenant reach?
The wording puts the act on God's side. He does not just point out something in nature. He gives it a meaning it did not carry before.
The bow is given as the token of the covenant; that does not mean it was created then. God could, of course, have put plenty of clouds above the earth without a rainbow. He says, "I do set my bow."
J. N. Darby (older translations read "I do set my bow in the cloud")
Commentators differ on whether the rainbow itself was new. One writer treats the question as unanswerable and points to the new meaning instead:
It is a pointless question, because Scripture has not given us enough evidence to settle it. Was the rainbow seen then for the first time, or was it well known in the earliest ages?... The least we can draw from the words is that God was now, after the flood, pleased to attach a new and merciful meaning to it.
The sign meets the moment when fear returns — when the sky darkens again.
So there is immense comfort in the bow God's goodness pledged when He set it in the cloud. As a rule you do not see it unless there is rain, and only when the sun shines behind you from the opposite side of the sky. No sign could fit better. If the rain might stir up fear, the beautiful bow had every right to calm it, because God Himself was pleased to assure man of His unfailing covenant.
Another writer holds the two halves together — the cloud God brings, and the bow God sets:
"I bring a cloud... I do set My bow." We may not separate these two, nor look at one apart from the other. It is good for us to remember that man — himself and his works — is only fit for judgment. It is just as good to remember what God is, or the soul must sink into despair.
The sign is not only for human eyes.
The bow in the cloud is man's assurance; but it is more, it is God's memorial of the new relationship into which He has entered with His creatures. His eye is on the bow, and not man's only. So He gives them fellowship with Himself in a sign that speaks of peace in the middle of trouble, and of light in the place of darkness.
The covenant this sign confirms carries no conditions for Noah to keep. This writer also takes the wording as proof that the rainbow itself was new:
This covenant made with Noah and all creation was unconditional. It was a covenant of promise, not depending on any faithfulness of the creature. It was something new. The words, "I do set My bow in the cloud," clearly imply that no one had ever seen a rainbow before.
The promise rules out one kind of judgment, not every judgment:
Another universal judgment by water will never come again (verse 15). Another judgment is in store for this planet. "The world that then existed was deluged with water and perished. But by the same word the heavens and earth that now exist are stored up for fire, being kept until the day of judgment and destruction of the ungodly."
The colours themselves carry meaning.
This is a lovely picture of God's glory, for "God is light." Each colour stands for some part of God's many attributes — supremacy, power, authority, grace, righteousness, holiness, love... So all the glory of God is bound up in His promise never again to judge the world by a universal flood.
That same pattern — glory shining out of a storm — appears again at the cross:
There was a cloud indeed — a dark, thick, heavy cloud of judgment pouring itself out on the sacred head of the Lamb of God... But, thank God, faith sees in that heaviest cloud that ever gathered the most brilliant and beautiful bow that ever appeared.
- Set, not found. God takes the bow and makes it His token. The covenant rests on His act of giving the sign, not on where the rainbow came from.
- Cloud, then bow. The sign appears only where there is cloud. God joins the reminder of judgment to the reminder of what He is, so fear does not turn into despair.
- His eye first. The bow is man's assurance, but it is also God's memorial. His own eye is on it, and that is why the promise holds.
- No conditions, wide reach. God makes the covenant with Noah, all creation, and the earth itself, and it depends on no faithfulness from the creature.
- Glory out of the storm. Colour after judgment pictures God showing His own glory — and faith sees that glory most clearly at the cross.
And it shall come to pass when I bring clouds over the earth, that the bow shall be seen in the cloud,
The bow set in the cloud is God's answer to a world that had just watched water swallow everything. So why did God tie the sign to the very thing people would fear most — the gathering cloud?
The promise attached to this sign asks nothing of Noah in return.
This covenant made with Noah and all creation was unconditional. It was a covenant of promise, not depending on any faithfulness of the creature. It was something new. The words, "I do set My bow in the cloud," clearly suggest that no one had ever seen a rainbow before.
Commentators differ on whether the rainbow itself was new. Others read the verb as appointment rather than creation:
The rainbow may have appeared to Noah before, but it was not appointed by God as a token until after the flood. The word translated "set" (nathan) is sometimes translated "appoint," as in Joshua 20:2. Others think it more likely that no one saw a rainbow before the flood, since the air was in a different state then from what it became after the flood.
The survivors of the flood had a reason to dread bad weather.
Men had good reason to tremble after that terrible disaster. Dark clouds covered the sky, the rain fell in torrents, and tidal waves rose with overwhelming force. An accusing conscience would speak even louder of the disaster they had just lived through. Man naturally expects that what happened once will happen again. He expects it all the more if old sins still ruled and new evils sprang up.
Notice that the verse names the cloud, not the rain — and that detail is exact.
As a rule you do not see it unless there is rain. And you see it only when the sun shines brightly at your back, from the opposite side of the sky. So no sign could be more fitting. If the rain might stir up fears, the glorious bow had every right to calm them. God Himself gladly chose this way to assure man of His unfailing covenant. The accuracy is even more striking. The words run, "When I bring clouds over the earth and the bow is seen in the clouds." Rain does not seem strictly necessary, but cloud is.
The verse says the bow will be seen. Scripture then adds that God Himself looks at it.
We look at the cloud; God looks at the bow. What grace is here! He says, "And the bow shall be in the cloud; and I will look upon it." The bow tells of God's unchangeable faithfulness and mercy when all is over with man. This is the ground we are on with God.
Cloud and bow appear together again in a scene of coming judgment.
The mighty angel, the angel of judgment, comes down. He is clothed with a cloud, the frightening vessel of wrath and sign of judgment. This is what God said at the beginning: "When I bring clouds over the earth." But even then the rainbow is with Him... It is not simply with a cloud He comes down, but with the cloud and the bow accompanying it. See Gen. 9:14; Rev. 10:1. This tells us that at the very end He remembers His word, and will hold judgment in check. He will say to it, "You may come this far, and no farther." ... The cloud carries out its commission and pours out its waters, or its judgments, again. But it must stop in obedience to the bow that measures and controls it.
Since God brings the cloud, the sign is meant for your own trouble too.
My fellow-believer, in all the trials of the way God would have us see the bow in the cloud. Think of this in your present trial, which He has allowed. Think of the thing that distresses you most of all, which perhaps no other Christian knows anything about. These words are written for you... The cloud may be dark and gloomy, but there is a beauty in it painted by His own hand, and it tells you, despite everything, what He is to you. And remember, whether you see it or not, IT IS THERE.
- Cloud. God fixed the sign to the very thing men feared after the flood: a sky filling with water again.
- Bow. He gives it as an unconditional promise. It rests on His faithfulness, not on anything Noah does.
- Seen. The bow appears only with cloud and with sunlight behind you. No sign could match the words of the verse better.
- Looked upon. Man watches the cloud; God watches the bow, and it is His eye on it that keeps the promise alive.
- Held back. Right to the last judgments, the cloud must stop where the bow says stop — so read your own dark sky the same way.
