C. F. Keil and Franz Delitzsch on Deuteronomy 13:13-14

Deu 13:13-14

The third case is that of a town that had been led away to idolatry. “If thou shalt hear in one of thy cities.” בּאחת, not de una, of one, which שׁמע with בּ never can mean, and does not mean even in Job 26:14. The thought is not that they would hear in one city about another, as though one city had the oversight over another; but there is an inversion in the sentence, “if thou hear, that in one of thy cities...worthless men have risen up, and led the inhabitants astray to serve strange gods.” לאמר introduces the substance of what is heard, which follows in Deu 13:14. יצא merely signifies to rise up, to go forth. מקּרבּך, out of the midst of the people.
