And the bow shall be in the cloud
Not whenever there is a cloud, but at some certain times, when that and the sun are in a proper position to form one, and when divine wisdom sees right there should be one; then it appears and continues for a time, and as the cloud becomes thinner and thinner, it disappears: and I will look upon it, that I may remember the everlasting
covenant between God and every living creature of all flesh that is
upon the earth;
not that forgetfulness, or remembrance, properly speaking, belong to God, but this is said after the manner of men; who by this token may be assured, whenever they see the bow in the cloud, that God is not unmindful of the covenant he has made with all creatures, and which is to continue to the end of the world.
