Shem and Japheth took a garment, and laid it on both their shoulders, went in backwards, and covered the nakedness of their father. Their faces were backwards, and they didn't see their father's nakedness.

Joseph remembered the dreams which he dreamed about them, and said to them, "You are spies! You have come to see the nakedness of the land."

He said to them, "No, but you have come to see the nakedness of the land!"
