John Calvin's Bible Commentary
Jeremiah 44:7
He then adds, Why then do ye now this great evil against your own souls, to cut off from you man and woman, child and suckling, from the midst of Judah, that nothing may remain for you? he re at length the passage is finished; for what we have hitherto read would have kept the reader in suspense, had not this been added. He then says, “Since the sin of your fathers ought to have been detested by you, and since God’s judgment had been dreadful, and that punishment ought at this day to fill, you with fear, how is it, that ye seek to bring on yourselves again the vengeance of God?” Why then, he says, now, etc. This now is emphatical, that is, after so many and so remarkable examples, after so many admonitions, after the most grievous punishment inflicted on the obstinate. He says, against your own souls; and by this he touched them very sharply, reminding them that what they were doing would be to their ruin, as though he had said, that God would receive no loss from their wickedness, but that they would become the authors of their own destruction, he indeed intimates, as I have already said, that their impiety would not be without its punishment; but he shews at the same time that God could, if he thought proper, look down with indifference on their impieties; for he would remain perfect even if they were the worst. For when God is robbed by men of his just and legitimate worship, there is nothing taken away from his greatness; for he ever remains the same, and is neither advanced nor diminished through the will of men. Then the Prophet shews that the Jews were acting madly for their own ruin, when he says, that they did evil against their own souls
And this he explains more fully by adding, To cut off man and woman, child and suckling, from the midst of Judah He intimates that God still manifested his mercy, while there was any remnant. They might have remained in Judea, even in their own inheritance; and the country might have been inhabited till the time of seventy years had elapsed, which God had fixed for the exile. Now the Prophet shews that they fought as it were against the goodness of God, for they sought to extinguish their own name, so that nothing should remain of that people, to whom God had still left some seed, that they might not wholly perish.
