Genesis 9:22-23

New American Standard Bible

²² Ham, the father of Canaan, ^(A)saw the nakedness of his father, and told his two brothers outside. ²³ But Shem and Japheth took a garment and laid it on both their shoulders and walked backward and covered the nakedness of their father; and their faces were ^[a]turned away, so that they did not see their father’s nakedness.
