Genesis 9:24

And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without.

And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father’s nakedness.

And he said, Cursed be Canaan; a servant of servants shall he be unto his brethren.

And he said, Blessed be the LORD God of Shem; and Canaan shall be his servant.
