And I polluted them in their own gifts, in that they caused to pass through the fire all that openeth the womb, that I might make them desolate, to the end that they might know that I am the LORD. I polluted them in their own gifts - I permitted them to pollute themselves by the offerings which they made to their idols. Causing their children to pass through the fire was one of those pollutions; but, did God ever give them a statute or judgment of this kind? No. He ever inveighs against such things, and they incur his heaviest displeasure and curse. See on Ezekiel 20:31 (note).
