Genesis 9:11-15

I will establish My covenant or pledge with you: Never again shall all flesh be cut off by the waters of a flood; neither shall there ever again be a flood to destroy the earth and make it corrupt. And God said, This is the token of the covenant (solemn pledge) which I am making between Me and you and every living creature that is with you, for all future generations: I set My bow [rainbow] in the cloud, and it shall be a token or sign of a covenant or solemn pledge between Me and the earth. And it shall be that when I bring clouds over the earth and the bow [rainbow] is seen in the clouds, I will [earnestly] remember My covenant or solemn pledge which is between Me and you and every living creature of all flesh; and the waters will no more become a flood to destroy and make all flesh corrupt.
