Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

The sons of Salma,.... Another son of the younger Caleb, Ch1 2:50 whose sons were Bethlehem, the inhabitants of the place, at least many of them, of which he was prince, Ch1 2:51 and the Netophathite; the inhabitants of Netophah, a place in the tribe of Judah, mentioned along with Bethlehem, Neh 7:26 these sprung from Salma: Ataroth, the house of Joab; Ataroth seems to be the name of a place in the tribe of Judah, where the family of Joab lived, the inhabitants of which were the descendants of Salma: and half of the Manahethites; the other half of the inhabitants of Manahath, see Ch1 2:52, the Zorites; part also of them, called Zareathites, Ch1 2:53.
