That they have committed adultery
Either literally, adultery with their neighbours' wives, which was a prevailing sin with this people; or figuratively, spiritual adultery, that is, idolatry: and blood is in their hands;
the Targum is,
``they have shed the blood of innocents with their hands;''the blood of prophets and righteous men, sent unto them; and the blood of their infants in sacrificing to idols, as after mentioned: and with their idols have they committed adultery;
by worshipping them, which is spiritual adultery; and this being so explicitly mentioned, it seems to be distinguished from corporeal adultery in the first clause, which may be only there designed; and so Kimchi thinks: and have also caused their sons, whom they bare unto me, to pass for
them through the fire, to devour them;
their children, who were the Lord's by national adoption, and who ought to have been trained up in the worship and service of God, were, in a most barbarous and unnatural manner, caused to pass through the fire, for or to the idols Molech and Baal; and that not merely by way of lustration and dedication, which was sometimes done by passing between two fires, but so as to be devoured and destroyed by the fire.
