'Idol sacrifices' in the Bible

but that we write to them, that they abstain from pollutions of idol [sacrifices], and from whoredom, and from what is strangled, and from blood.

Concerning the Gentiles who have believed, we have already written, deciding that they should observe no such thing, except that they should guard themselves from idol sacrifices, and blood, and what is strangled, and from whoredom.

Yet I have a few things against thee, that thou hast there some who hold the doctrine of Balaam, who taught Balac to lay a stumbling-block before the children of Israel, to eat of idol sacrifices, and to commit whoredom.

Yet I have a few things against thee, because thou hast suffered that woman Jezabel, calling herself a prophetess, to teach, and to lead my servants into error, to commit whoredom, and eat the idol sacrifices.
