2 Kings 18:3-6

He did what was right in the eyes of the LORD, just as his father David had done. He 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.) Hezekiah trusted in the LORD, the God of Israel. There was no-one like him among all the kings of Judah, either before him or after him. He held fast to the LORD and did not stop following him; he kept the commands the LORD had given Moses.
