And she answered him, Nay, my brother, do not force me; for no such thing ought to be done in Israel: do not thou this folly.

Wesley's Notes

13:12 Brother - Whom nature both teaches to abhor such thoughts and obliges to defend me from such a mischief with thy utmost hazard, if another should attempt it. Force - Thou shouldst abhor it, if I were willing; but to add violence, is abominable. Israel - Among God's people who are taught better things; who also will be infinitely reproached for such a base action.

King James Translators' Notes

force...: Heb. humble me

no such...: Heb. it ought not so to be done

Jamieson-Fausset-Brown Bible Commentary

12-14. do not force me-The remonstrances and arguments of Tamar were so affecting and so strong, that had not Amnon been violently goaded on by the lustful passion of which he had become the slave, they must have prevailed with him to desist from his infamous purpose. In bidding him, however, "speak to the king, for he will not withhold me from thee," it is probable that she urged this as her last resource, saying anything she thought would please him, in order to escape for the present out of his hands.

Matthew Henry's Concise Commentary

13:1-20 From henceforward David was followed with one trouble after another. Adultery and murder were David's sins, the like sins among his children were the beginnings of his punishment: he was too indulgent to his children. Thus David might trace the sins of his children to his own misconduct, which must have made the anguish of the chastisement worse. Let no one ever expect good treatment from those who are capable of attempting their seduction; but it is better to suffer the greatest wrong than to commit the least sin.
