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.
