Genesis 9:20

16The rainbow will be in the cloud. I will look at it, that I may remember the everlasting covenant between God and every living creature of all flesh that is on the earth.”

17God said to Noah, “This is the token of the covenant which I have established between me and all flesh that is on the earth.”

18The sons of Noah who went out from the ship were Shem, Ham, and Japheth. Ham is the father of Canaan.

19These three were the sons of Noah, and from these the whole earth was populated.

20Noah began to be a farmer, and planted a vineyard.

21He drank of the wine and got drunk. He was uncovered within his tent.

22Ham, the father of Canaan, saw the nakedness of his father, and told his two brothers outside.

23Shem and Japheth took a garment, and laid it on both their shoulders, went in backwards, and covered the nakedness of their father. Their faces were backwards, and they didn’t see their father’s nakedness.

24Noah awoke from his wine, and knew what his youngest son had done to him.
