Genesis 9:20-27

Then Noah began farming and planted a vineyard. He drank of the wine and became drunk, and uncovered himself inside his tent. Ham, the father of Canaan, saw the nakedness of his father, and told his two brothers outside. But Shem and Japheth took a garment and laid it upon both their shoulders and walked backward and covered the nakedness of their father; and their faces were turned away, so that they did not see their father’s nakedness. When Noah awoke from his wine, he knew what his youngest son had done to him. So he said, “Cursed be Canaan; A servant of servants He shall be to his brothers.” He also said, “Blessed be the LORD, The God of Shem; And let Canaan be his servant. May God enlarge Japheth, And let him dwell in the tents of Shem; And let Canaan be his servant.”
