2 Kings 18:4-5

He 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]. [Num 21:8] Hezekiah trusted in and relied confidently on the LORD, the God of Israel; so that after him there was no one like him among all the kings of Judah, nor among those who were before him.
