Verse 15. - And I will remember (cf. Genesis 8:1). An anthropomorphism introduced to remind man that God is ever faithful to his covenant engagements (Calvin). "God is said to remember, because he maketh us to know and to remember" (Chrysostom). My covenant (vide on ver. 11), which is between me and you and every living creature of all flesh; and the waters shall no more become a flood - hayah with le - to become (cf. Genesis 2:7); literally, shall no more be (i.e. grow) to a flood; or, "and there shell no more be the waters to the extent of a flood " - to destroy all flesh.

9:8-17 As the old world was ruined, to be a monument of justice, so this world remains to this day a monument of mercy. But sin, that drowned the old world, will burn this. Articles of agreement among men are sealed, that what is promised may be the more solemn, and the doing of what is covenanted the more sure to mutual satisfaction. The seal of this covenant was the rainbow, which, it is likely, was seen in the clouds before, but was never a seal of the covenant till now it was made so. The rainbow appears when we have most reason to fear the rain prevailing; God then shows this seal of the promise, that it shall not prevail. The thicker the cloud, the brighter the bow in the cloud. Thus, as threatening afflictions abound, encouraging consolations much more abound. The rainbow is the reflection of the beams of the sun shining upon or through the drops of rain: all the glory of the seals of the covenant are derived from Christ, the Sun of righteousness. And he will shed a glory on the tears of his saints. A bow speaks terror, but this has neither string nor arrow; and a bow alone will do little hurt. It is a bow, but it is directed upward, not toward the earth; for the seals of the covenant were intended to comfort, not to terrify. As God looks upon the bow, that he may remember the covenant, so should we, that we may be mindful of the covenant with faith and thankfulness. Without revelation this gracious assurance could not be known; and without faith it can be of no use to us; and thus it is as to the still greater dangers to which all are exposed, and as to the new covenant with its blessings.And I will remember my covenant which is between me and you, and every living creature of all flesh,.... See Genesis 9:11.

and the waters shall no more become a flood to destroy all flesh; this is repeated to remove those fears which would naturally arise, upon the gathering of the clouds in the heavens; but as God would remember his covenant, which he can never forget; and is always mindful of, so men, when they see the bow in the cloud, may be assured, that whatever waters are in the heavens, they shall never be suffered to fall in such quantity as to destroy all creatures as they have done.
