He sacrificed his sons in the fire in the Valley of Hinnom. He practiced sorcery, divination, and witchcraft, and consulted mediums and spiritists. He did great evil in the sight of the LORD, provoking Him to anger.
Jewish Publication Society of America Version (JPS1917) - 2 Chronicles 33:6 >He also made his children to pass through the fire in the valley of the son of Hinnom; and he practised soothsaying, and used enchantments, and practised sorcery, and appointed them that divined by a ghost or a familiar spirit; he wrought much evil in the sight of the LORD, to provoke Him.
