'Abomination' in the Bible

They served him by himself, and them by themselves, and the Egyptians, that ate with him, by themselves, because the Egyptians don't eat bread with the Hebrews, for that is an abomination to the Egyptians.

that you shall say, 'Your servants have been keepers of livestock from our youth even until now, both we, and our fathers:' that you may dwell in the land of Goshen; for every shepherd is an abomination to the Egyptians."
