John Gill Commentary 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 augury, and used enchantments, and practised sorcery, and dealt with them that had familiar spirits, and with wizards: he wrought much evil in the sight of Jehovah, to provoke him to anger." — 2 Chronicles 33:6 (ASV)
