"So they left all the commandments of the Lord their God, made for themselves a molded image and two calves, made a wooden image and worshiped all the host of heaven, and served Baal. And they caused their sons and daughters to pass through the fire, practiced witchcraft and soothsaying, and sold themselves to do evil in the sight of the Lord, to provoke Him to anger." II Kings

"Moreover you took your sons and your daughters, whom you bore to Me, and these you sacrificed to them to be devoured. Were your acts of harlotry a small matter, that you have slain My children and offered them up to them by causing them to pass through the fire?" Ezekiel

"When you offer your gifts and make your sons pass through the fire, you defile yourselves with all your idols" Ezekiel
