Genesis 43:31-33

New Revised Standard Version, Anglicised Catholic Edition

³¹ Then he washed his face and came out; and controlling himself he said, ‘Serve the meal.’ ³² They served him by himself, and them by themselves, and the Egyptians who ate with him by themselves, because the Egyptians could not eat with the Hebrews, for that is an abomination to the Egyptians. ³³ When they were seated before him, the firstborn according to his birthright and the youngest according to his youth, the men looked at one another in amazement.
