You must burn the carved images of their gods with fire. You are not to covet the silver or the gold that is on them, nor take it for yourself, lest you be snared in it; for it is an abomination to Yahweh your God. Bible

“burn the carved images of their gods.” Most idols and images of gods were made from wood or stone and could be burned in a fire. Much of the stone in Israel is limestone and is reduced to powder when it is heated very hot, and also the ancients used to take the harder stone, such as basalt or granite and heat it up and then pour water on it to break it up. [For more on what God said about idols, see commentary on Deut. 7:5].
