'Abomination' in the Bible

So the servants served Joseph by himself [in honor of his rank], and his brothers by themselves, and the Egyptians who ate with him by themselves, because [according to custom] the Egyptians could not eat food with the Hebrews, for that is loathsome to the Egyptians.

you shall say, ‘Your servants have been keepers of livestock from our youth until now, both we and our fathers [before us],’ in order that you may live [separately and securely] in the land of Goshen; for every shepherd is repulsive to the Egyptians.”
