'Idol' in the Bible

And he set the graven image of the idol, which he had made, in the house of God, of which God said to David and to Solomon his son, In this house, and in Jerusalem, which I have chosen out of all the tribes of Israel, will I put my name for ever:

And he took away the foreign gods, and the idol out of the house of Jehovah, and all the altars that he had built in the mount of the house of Jehovah, and in Jerusalem, and cast them out of the city.

therefore I have declared it to thee from of old; before it came to pass I showed it thee; lest thou shouldest say, Mine idol hath done them, and my graven image, and my molten image, hath commanded them.

He that killeth an ox is as he that slayeth a man; he that sacrificeth a lamb, as he that breaketh a dog's neck; he that offereth an oblation, as he that offereth'swine's blood; he that burneth frankincense, as he that blesseth an idol. Yea, they have chosen their own ways, and their soul delighteth in their abominations:

And they made a calf in those days, and brought a sacrifice unto the idol, and rejoiced in the works of their hands.

Concerning therefore the eating of things sacrificed to idols, we know that no idol is anything in the world, and that there is no God but one.

Howbeit there is not in all men that knowledge: but some, being used until now to the idol, eat as of a thing sacrificed to an idol; and their conscience being weak is defiled.

For if a man see thee who hast knowledge sitting at meat in an idol's temple, will not his conscience, if he is weak, be emboldened to eat things sacrificed to idols?

What say I then? that a thing sacrificed to idols is anything, or that an idol is anything?
