2 Kings 18:3-6

3And he did what was right in the eyes of the LORD, according to all that David his father had done. 4He removed the high places and broke the pillars and cut down the Asherah. And he broke in pieces the bronze serpent that Moses had made, for until those days the people of Israel had made offerings to it (it was called Nehushtan). 5He trusted in the LORD, the God of Israel, so that there was none like him among all the kings of Judah after him, nor among those who were before him. 6For he held fast to the LORD. He did not depart from following him, but kept the commandments that the LORD commanded Moses.
