"I am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before me. You shall not make for yourself a carved image-- any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them or serve them."
"And the person who turns to mediums and familiar spirits, to prostitute himself with them, I will set My face against that person and cut him off from his people."
"There shall not be found among you anyone who makes his son or daughter pass through the fire, or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead."
"Asa did what was right in the eyes of the Lord, as did his father David. And he banished the perverted persons from the land and removed the idols that his fathers had made. Also he removed Maachah his grandmother from being queen mother, because she had made an obscene image of Asherah. And Asa cut down her obscene image and burned it by the brook Kidron."
(1 Kings 15:11-13)
"And the king [Josiah] commanded Hilkiah the high priest, the priests of the second order, and the doorkeepers, to bring out of the temple of the Lord all the articles that were made for Baal, for Asherah, and for all the host of heaven; and he burned them them outside Jerusalem in the fields of Kidron, and carried their ashes to Bethel."
(2 Kings 23:4)
"Do not be unequally yoked together with unbelievers....What agreement has the temple of God with idols?"
(2 Corinthians 6:14,16)
"But I fear, lest somehow, as the serpent deceived Eve by his craftiness, so your minds may be corrupted from the simplicity that is in Christ. For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted-- you may well put up with it! ....For such are false apostles, deceitful workers, transforming themselves into apostles of Christ. And no wonder! For Satan himself transforms himself into an angel of light."
(2 Corinthians 11:3-4,13-14)
