2 Kings 16:2-4

2Twenty years old was Ahaz when he began to reign, and reigned sixteen years in Jerusalem, and did not that which was right in the sight of the LORD his God, like David his father. 3But he walked in the way of the kings of Israel, and even made his son to pass through the fire, according to the abominations of the heathen, whom the LORD cast out from before the children of Israel. 4And he sacrificed and burnt incense in the high places, and on the hills, and under every green tree.
