'Detestable' in the Bible

Joseph's staff served him by himself, his brothers separately, and the Egyptian staff members by themselves, because the Egyptians wouldn't take their meal with the Hebrews, since doing so was detestable for the Egyptians.

you are to tell him, "Your servants have been taking care of livestock since we were youths. We and our ancestors have taken care of livestock.' That way, you'll be able to live in the Goshen territory, since shepherds are detestable to the Egyptians."
