Numbers 25:2

Lest thou make a covenant with the inhabitants of the land, and they go a whoring after their gods, and do sacrifice unto their gods, and one call thee, and thou eat of his sacrifice;

Is the iniquity of Peor too little for us, from which we are not cleansed until this day, although there was a plague in the congregation of the LORD,

But king Solomon loved many strange women, together with the daughter of Pharaoh, women of the Moabites, Ammonites, Edomites, Zidonians, and Hittites: Of the nations concerning which the LORD said unto the children of Israel, Ye shall not go in to them, neither shall they come in unto you: for surely they will turn away your heart after their gods: Solomon clave unto these in love. And he had seven hundred wives, princesses, and three hundred concubines: and his wives turned away his heart. For it came to pass, when Solomon was old, that his wives turned away his heart after other gods: and his heart was not perfect with the LORD his God, as was the heart of David his father. For Solomon went after Ashtoreth the goddess of the Zidonians, and after Milcom the abomination of the Ammonites. And Solomon did evil in the sight of the LORD, and went not fully after the LORD, as did David his father. Then did Solomon build an high place for Chemosh, the abomination of Moab, in the hill that is before Jerusalem, and for Molech, the abomination of the children of Ammon. And likewise did he for all his strange wives, which burnt incense and sacrificed unto their gods.

They joined themselves also unto Baalpeor, and ate the sacrifices of the dead.

I found Israel like grapes in the wilderness; I saw your fathers as the firstripe in the fig tree at her first time: but they went to Baalpeor, and separated themselves unto that shame; and their abominations were according as they loved.

But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils.
