'Sacrificed' in the Bible

Yet I have a few things against you, because you have with you some that cling to the teaching of Balaam, who taught Balak to put a stumbling-block in the way of the descendants of Israel--to eat what had been sacrificed to idols, and commit fornication.

Yet I have this against you, that you tolerate the woman Jezebel, who calls herself a prophetess and by her teaching leads astray My servants, so that they commit fornication and eat what has been sacrificed to idols.

When the Lamb broke the fifth seal, I saw at the foot of the altar the souls of those whose lives had been sacrificed because of the word of God and of the testimony which they had given.
