Matthew Henry on 1 Chronicles 2:18–end
The persons mentioned in the former paragraph are most of them such as we read of, and most of them such as we read much of, in other scriptures; but very few of those to whom this paragraph relates are mentioned any where else. It should seem, the tribe of Judah were more full and exact in their genealogies than any other of the tribes, in which we must acknowledge a special providence, for the clearing of the genealogy of Christ. 1.

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.
