Ezekiel 23:37

that they have committed adultery, and blood is in their hands, the blood of unlawful sacrifices; and with their idols have they committed adultery, for the spiritual adultery of idol-worship was often connected with physical adultery and immorality of the worst kind, and have also caused their sons, whom they bare unto Me, to pass for them through the fire, to devour them, in the hideous and repulsive Molech cult.
