And he made his son pass through the fire and burned him as an offering [to Molech]; he practiced soothsaying and augury, and dealt with mediums and wizards! He did much wickedness in the sight of the Lord, provoking Him to anger. (AMP)
And he made his son pass through the fire, and observed times, and used enchantments, and dealt with familiar spirits and wizards: he wrought much wickedness in the sight of the LORD, to provoke him to anger. (KJV)
