1. Chronik 9:19

And Zechariah the son of Meshelemiah,.... Some think this refers to one that was in the times of David; but it seems rather to respect one that was after the Babylonish captivity, see Ch1 26:1 though he and his brethren were in an office established in the times of David, and the order of which was now, as then, observed: was porter of the door of the tabernacle of the congregation: who was the chief porter, and kept the door; either that led into the outer court, and kept out all unclean persons from entering there; or that which led into the court of the priests, that none but priests might enter there.

This chapter intimates to us that one end of recording all these genealogies was to direct the Jews, now that they had returned out of captivity, with whom to incorporate and where to reside; for here we have an account of those who first took possession of Jerusalem after their return from Babylon, and began the rebuilding of it upon the old foundation. I. The Israelites (Ch1 9:2-9). II. The priests (Ch1 9:10-13). III. The Levites and other Nethinim (Ch1 9:14-26). IV. Here is the particular charge of some of the priests and Levites (Ch1 9:27-34). V. A repetition of the genealogy of king Saul (Ch1 9:35-44).
