2 Kings 21:2-6, 11, 16

He did evil in the sight of the LORD, according to the abominations of the nations whom the LORD dispossessed before the sons of Israel. For he rebuilt the high places which Hezekiah his father had destroyed; and he erected altars for Baal and made an Asherah, as Ahab king of Israel had done, and worshiped all the host of heaven and served them. He built altars in the house of the LORD, of which the LORD had said, “In Jerusalem I will put My name.” For he built altars for all the host of heaven in the two courts of the house of the LORD. He made his son pass through the fire, practiced witchcraft and used divination, and dealt with mediums and spiritists. He did much evil in the sight of the LORD provoking Him to anger.

“Because Manasseh king of Judah has done these abominations, having done wickedly more than all the Amorites did who were before him, and has also made Judah sin with his idols

Moreover, Manasseh shed very much innocent blood until he had filled Jerusalem from one end to another; besides his sin with which he made Judah sin, in doing evil in the sight of the LORD.
