Deuteronomy 7:5, 25

But thus you shall do to them: you shall tear down their altars, and smash their sacred pillars, and hew down their Asherim, and burn their graven images with fire.

The graven images of their gods you are to burn with fire; you shall not covet the silver or the gold that is on them, nor take it for yourselves, or you will be snared by it, for it is an abomination to the LORD your God.
