Genesis 9:21-23

Wycliffe Bible

²¹ and (one day) he drank wine, and was drunken; and he was naked, and lay in his tabernacle (and he lay naked in his tent).

²² And when Ham, the father of Canaan, had seen this thing, that is, that the shameful members of his father were made naked, he told his two brethren withoutforth.

²³ And Shem and Japheth putted a mantle on their shoulders, and they went backward, and covered the shameful members of their father, and their faces were turned away, and they saw not the privy members of their father.
