2 Kings 16:2-3

2Ahaz was twenty years old when he became king, and he reigned sixteen years in Jerusalem; and he did not do what was right in the sight of the Lord his God, as his father David had done.

3But he walked in the way of the kings of Israel; indeed he made his son pass through the fire, according to the abominations of the nations whom the Lord had cast out from before the children of Israel.
