Bring her forth to the magistrate, from whom she may receive her sentence and deserved punishment. Judah had not the power of life and death, at least not over her, who was a Canaanite, and who was not in his, but in her own father's house. But he being a person of great estate and authority, and, as it seems, of obliging conversation, could do very much to persuade those who then had the power of the sword, either to draw it forth, at least in a just cause, on his behalf, or to sheath it upon his desire and satisfaction. Let her be burnt, as guilty of adultery, which was punished with death by the laws of God, Deuteronomy 22:23,24, and of nations too, Jeremiah 29:22,23. He chargeth her with adultery, because she was betrothed to Shelah. See Deuteronomy 22:23. This eagerness of Judah proceeded not from zeal of justice, for then he would not have endeavoured to destroy the innocent child with the guilty mother, against God's law, Deuteronomy 24:16 Ezekiel 18:20, but from worldly policy, that he might take her out of the way, which he esteemed a burden and a blot to his family.
