Genesis 46:34

So they set the meal for him by himself, and for them by themselves, and for the Egyptians who ate with him by themselves, because the Egyptians could not eat bread with the Hebrews, for that is an abomination to the Egyptians.

“And you shall live in the land of Goshen, and you shall be near me, you and your children and your children’s children and your flocks and your herds and all that you have.

Then Pharaoh said to his brothers, “What is your occupation?” So they said to Pharaoh, “Your servants are shepherds, both we and our fathers.”

And they said to Pharaoh, “We have come to sojourn in the land, for there is no pasture for your servants’ flocks, for the famine is heavy in the land of Canaan. So now, please let your servants live in the land of Goshen.”

But Moses said, “It is not right to do so, for we will sacrifice to Yahweh our God what is an abomination to the Egyptians. If we sacrifice what is an abomination to the Egyptians before their eyes, will they not then stone us?
