(12) Do not thou this folly.--Tamar, now left alone in the power of her half-brother, endeavours to escape by reasoning. She first speaks of the sinfulness in Israel of that which was allowed among surrounding heathen, quoting the very words of Genesis 34:7, as if by the traditions of their nation to recall the king's son to a sense of right. She then sets forth the personal consequences to themselves; if he had any love for her he could not wish that shame and contempt should meet her everywhere; and for himself, such an act would make him "as one of the fools in Israel," as one who had cast off the fear of God and the restraints of decency.

Verse 12. - Do not force me; literally, do not humble me. It is to be regretted that the word should be changed, as it bears testimony to the nobleness of the Hebrew women, who regarded their chastity as their crown of honour. The word folly is used in the sense of unchastity in Genesis 34:7 and elsewhere, and it is noteworthy that the Jews thus connected crime with stupidity. Vain, that is, empty persons were the criminal part of the population (Judges 9:4), and to call a man "a fool" was to attribute to him every possible kind of wickedness (Matthew 5:22). The thought which lay at the root of this view of sin was that Israel was a peculiar people, sanctified to God's service; and all unholiness, therefore, was not merely criminal in itself, but a proof that the guilty person was incapable of rightly estimating his privileges. Tamar urges this upon her "empty" brother, and then pathetically dwells upon their mutual shame, and, finding all in vain, she even suggests that the king might permit their marriage. Such marriages, between half-brothers and half-sisters were strictly forbidden, as tending to loosen the bends of family purity (Leviticus 18:9; Deuteronomy 27:22); but possibly the Levitical code was occasionally violated, or Tamar may have suggested it in the hope of escaping immediate violence.

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.And she answered him, nay, my brother,.... Which carried in it a reason sufficient for her denial, that he was her brother, and she his sister, and therefore should not offer such an indignity to her:

do not force me; which was another forbidding expression, signifying she would never freely yield to his will; and to force her, to defile her against her will, to commit a rape upon her, would be very criminal indeed:

for no such thing ought to be done in Israel; among God's professing people, who were better taught and instructed; and to give into such impure practices would bring a dishonour upon them, and upon the religion they professed; she urges the honour of religion, and the reputation of Israel, and the glory of the God of Israel:

do not thou this folly: as all sin is, especially such an impure and indecent action as this.
