John Gill Bible Commentary

Therefore now thus saith the Lord, the God of hosts, the God of Israel,.... The same epithets as before, Jer 44:2; with an addition, that his words might carry more weight with them: wherefore commit ye this great evil against your souls; the sin of idolatry, which is a great evil; a sin against God; a giving the glory to another, that belongs to him and not only so, but is against the souls of men; pernicious and ruinous to them, which brings destruction, even eternal wrath and damnation, on them; and this is an interesting argument why it should not be committed; nay, it was not only against God, and against themselves, but against their families, and the interest of them: to cut off from you man and woman, child and suckling, out of Judah, to leave you none to remain; not that they did this great evil or committed idolatry with this intention, to ruin their families and posterity; but so it was eventually; hereby they provoked the Lord to anger, to cut off the men that offered incense to idols; and the women their wives, whom they allowed so to do; and their children, who were brought up in the same practices; so that they would have none to succeed them, to bear their name, and inherit their land; unless God should be merciful, and not deal according to their deserts; for such was the nature of their crime, as to deserve an utter extirpation of them.
