²²  And Ham the father of Canaan saw the nakedness of his father, and told his two brethren outside.

²³  And Shem and Japheth took the upper garment and both laid [it] upon their shoulders, and went backwards, and covered the nakedness of their father. And their faces were turned away, that they saw not their father's nakedness.

²⁴  And Noah awoke from his wine, and learned what his youngest son had done to him.

²⁵  And he said, Cursed be Canaan; Let him be a bondman of bondmen to his brethren.
