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.
