2 Kings 21:2-6, 11, 16

He did [great] evil in the sight of the LORD, in accordance with the [idolatrous] repulsive acts of the [pagan] nations whom the LORD dispossessed before the sons (descendants) of Israel. For he rebuilt the high places [for the worship of pagan gods] which his father Hezekiah had destroyed; and he set up altars for Baal and made an [image of] Asherah, just as Ahab king of Israel had done, and he worshiped all the [starry] host of heaven and served them. And he built [pagan] altars in the house (temple) of the LORD, of which the LORD had said, “In Jerusalem I will put My Name (Presence).” And he built altars for all the host of heaven in the two courtyards of the house of the LORD. He made his son pass through the fire and burned him [as an offering to Molech]; he practiced witchcraft and divination, and dealt with mediums and soothsayers. He did great evil in the sight of the LORD, provoking Him to anger.

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

Moreover, Manasseh shed a very great quantity of innocent blood, until he had filled Jerusalem from one end to another; besides his sin with which he made Judah sin, by doing evil in the sight of the LORD. [2 Chr 33:1-10]
