²¹ And he drank of the yayin, and became shikker (intoxicated); and he lay uncovered inside his ohel.

²² And Cham, the av of Kena’an, saw the erom (nakedness) of his av, and told his two achim on the outside.

²³ And Shem and Yephet took a garment, and laid it upon both their shoulders, and walked backward, and covered the erom of their av; and their faces were turned the other way, and they saw not the erom of their av.
