Genesis 9:22-24

Brenton(i) 22 And Cham the father of Chanaan saw the nakedness of his father, and he went out and told his two brothers without. 23 And Sem and Japheth having taken a garment, put it on both their backs and went backwards, and covered the nakedness of their father; and their face was backward, and they saw not the nakedness of their father. 24 And Noe recovered from the wine, and knew all that his younger son had done to him.
