Genesis 43:32-33

43:32 They set a place for him, a separate place for his brothers, and another for the Egyptians who were eating with him. (The Egyptians are not able to eat with Hebrews, for the Egyptians think it is disgusting to do so.) 43:33 They sat before him, arranged by order of birth, beginning with the firstborn and ending with the youngest. The men looked at each other in astonishment.
