2 Kings 18:3-4

3Hezekiah did right in the sight of the Lord, in accordance with everything that David his father (ancestor) had done.

4He removed the high places [of pagan worship], broke down the images (memorial stones) and cut down the Asherim. He also crushed to pieces the bronze serpent that Moses had made, for until those days the Israelites had burned incense to it; and it was called Nehushtan [a bronze sculpture].
