Genesis 9:20-24

Noah began to be a farmer, and planted a vineyard. He drank of the wine and got drunk. He was uncovered within his tent. Ham, the father of Canaan, saw the nakedness of his father, and told his two brothers outside. Shem 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. Noah awoke from his wine, and knew what his youngest son had done to him.
