Exodus 8:26

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.

then you shall say, ‘Your servants have been keepers of livestock from our youth and until now, both we and our fathers,’ that you may live in the land of Goshen; for every shepherd is an abomination to the Egyptians.”

“Then You performed signs and wonders against Pharaoh, Against all his servants and all the people of his land; For You knew that they acted presumptuously toward them, And made a name for Yourself as it is this day.
