1-а хроніки 9:20

All those that were chosen to be porters in the gates were two hundred and twelve,.... As fixed in the days of David, and might not be fewer: these were reckoned by their genealogies in their villages; where they dwelt: whom David and Samuel the seer did ordain in their set office; the scheme was first drawn by Samuel the prophet, and communicated to David, who put it into execution, to be constantly and perpetually observed.

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).
