Genesis 9:18-23 NLT

18 The sons of Noah who came out of the boat with their father were Shem, Ham, and Japheth. (Ham is the father of Canaan.)
19 From these three sons of Noah came all the people who now populate the earth.
20 After the flood, Noah began to cultivate the ground, and he planted a vineyard.
21 One day he drank some wine he had made, and he became drunk and lay naked inside his tent.
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.
