Genesis 43:32-33

King James Version

³² And they set on for him by himself, and for them by themselves, and for the Egyptians, which did eat with him, by themselves: because the Egyptians might not eat bread with the Hebrews; for that is an abomination unto the Egyptians.

³³ And they sat before him, the firstborn according to his birthright, and the youngest according to his youth: and the men marvelled one at another.
