Genesis 9:23 YLT

²¹  and drinketh of the wine, and is drunken, and uncovereth himself in the midst of the tent.

²²  And Ham, father of Canaan, seeth the nakedness of his father, and declareth to his two brethren without.

²³  And Shem taketh -- Japheth also -- the garment, and they place on the shoulder of them both, and go backward, and cover the nakedness of their father; and their faces 'are' backward, and their father's nakedness they have not seen.

²⁴  And Noah awaketh from his wine, and knoweth that which his young son hath done to him,

²⁵  and saith: 'Cursed 'is' Canaan, Servant of servants he is to his brethren.'
