2 Kings 18:3-4

3He did what was right in the eyes of the LORD, just as his father David had done.

4He removed the high places, smashed the sacred stones and cut down the Asherah poles. He broke into pieces the bronze snake Moses had made, for up to that time the Israelites had been burning incense to it. (It was called Nehushtan. Nehushtan sounds like the Hebrew for both bronze and snake. )
