Genesis 9:20-23

Noah, a farmer, was the first to plant a vineyard. He drank from its wine, got drunk and passed out, naked in his tent. Ham, the father of Canaan, saw that his father was naked and told his two brothers who were outside the tent. Shem and Japheth took a cloak, held it between them from their shoulders, walked backward and covered their father’s nakedness, keeping their faces turned away so they did not see their father’s exposed body.
