Genesis 9:20-25 NIV

[20] Noah, a man of the soil, proceeded to plant a vineyard. [21] When he drank some of its wine, he became drunk and lay uncovered inside his tent. [22] Ham, the father of Canaan, saw his father naked and told his two brothers outside. [23] But Shem and Japheth took a garment and laid it across their shoulders; then they walked in backward and covered their father’s naked body. Their faces were turned the other way so that they would not see their father naked. [24] When Noah awoke from his wine and found out what his youngest son had done to him, [25] he said, “Cursed be Canaan! The lowest of slaves will he be to his brothers.”
