Genesis 9:22-24

New Living Translation

²² Ham, the father of Canaan, saw that his father was naked and went outside and told his brothers. ²³ Then Shem and Japheth took a robe, held it over their shoulders, and backed into the tent to cover their father. As they did this, they looked the other way so they would not see him naked.

²⁴ When Noah woke up from his stupor, he learned what Ham, his youngest son, had done.
