'Abomination' in the Bible

And they set on for him by himself, and for them by themselves, and for the Egyptians who ate with him by themselves; because the Egyptians might not eat bread with the Hebrews, for that is an abomination unto the Egyptians.

then ye shall say, Thy servants are men that have been occupied with cattle from our youth even until now, both we and our fathers; in order that ye may dwell in the land of Goshen; for every shepherd is an abomination to the Egyptians.
