'Idol' in the Bible

But I have a few things against thee: that thou hast there those who hold the doctrine of Balaam, who taught Balak to cast a snare before the sons of Israel, to eat of idol sacrifices and commit fornication.

But I have against thee that thou permittest the woman Jezebel, she who calls herself prophetess, and she teaches and leads astray my servants to commit fornication and eat of idol sacrifices.

But to the cowards, unbelievers, detestable persons, murderers, the sexually immoral, and those who practice magic spells, idol worshipers, and all those who lie, their place will be in the lake that burns with fire and sulfur. That is the second death."
