12:31 And he brought forth the people that [were] therein, and put [them] under {t} saws, and under harrows of iron, and under axes of iron, and made them pass through the brickkiln: and thus did he unto all the cities of the children of Ammon. So David and all the people returned unto Jerusalem.
(t) Signifying that as they were malicious enemies of God, so he put them to cruel death.
12:31 The people - The words are indefinite, and therefore not necessarily to be understood of all the people; but of the men of war, and especially of those who had been the chief actors of that villainous action against David's ambassadors, and of the dreadful war ensuing upon it; for which, they deserved severe punishments. Altho' indeed there seems to have been too much rigour used; especially, because these deaths were inflicted not only upon those counsellors, who were the only authors of that vile usage of the ambassadors; but upon some number of the people. And therefore it is probable, David exercised this cruelty whilst his heart was hardened, and impenitent; and when he was bereaved of that good spirit of God, which would have taught him more mercy. Saws - He sawed them to death of which punishment, we have examples both in scripture, and in other authors. Brick - kiln - Or, made them to pass through the furnace of Malchen: that is, of Moloch; punishing them with their own sin, and with the same kind of punishment which they had inflicted upon their own children.
12:26-31 To be thus severe in putting the children of Ammon to slavery was a sign that David's heart was not yet made soft by repentance, at the time when this took place. We shall be most compassionate, kind, and forgiving to others, when we most feel our need of the Lord's forgiving love, and taste the sweetness of it in our own souls.
