Genesis 9:18 (KJV)

I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.

And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud:

And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh.

And the bow shall be in the cloud; 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.

And God said unto Noah, This is the token of the covenant, which I have established between me and all flesh that is upon the earth.

These are the three sons of Noah: and of them was the whole earth overspread.

And Noah began to be an husbandman, and he planted a vineyard:

And he drank of the wine, and was drunken; and he was uncovered within his tent.

And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without.

And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father's nakedness.
