I Chronicles 9:2

Now the first inhabitants - This is spoken of those who returned from the Babylonish captivity, and of the time in which they returned; for it is insinuated here that other persons afterwards settled at Jerusalem, though these mentioned here were the first on the return from the captivity. Properly speaking, the divisions mentioned in this verse constituted the whole of the Israelitish people, who were, ever since the days of Joshua, divided into the four following classes: 1. The priests. 2. The Levites. 3. The common people, or simple Israelites. 4. The Nethinim, or slaves of the temple, the remains of the Gibeonites, who, having deceived Joshua, were condemned to this service Jos 9:21, etc. In David's time it is probable that other conquered people were added, as the successors of the Gibeonites were not sufficient to perform all the drudgery of the temple service.

the first inhabitants that dwelt in their possessions--This chapter relates wholly to the first returned exiles. Almost all the names recur in Nehemiah (Neh. 11:1-36), although there are differences which will be explained there. The same division of the people into four classes was continued after, as before the captivity; namely, the priests, Levites, natives, who now were called by the common name of Israelites, and the Nethinims (Jos 9:27; Ezr 2:43; Ezr 8:20). When the historian speaks of "the first inhabitants that dwelt in their possessions," he implies that there were others who afterwards returned and settled in possessions not occupied by the first. Accordingly, we read of a great number returning successively under Ezra, Nehemiah, and at a later period. And some of those who returned to the ancient inheritance of their fathers, had lived before the time of the captivity (Ezr 3:12; Hag 2:4, Hag 2:10).

Now the first inhabitants that dwelt in their possessions in their cities,.... Who first returned from Babylon upon the proclamation of Cyrus, and enjoyed their former possessions, and dwelt in the cities they had before, or in such as were allotted them, or they chose: were, the Israelites, the priests, Levites, and the Nethinims; the whole body that returned were divided into four classes, as they had been before the captivity; the Israelites were the common people in general, the body politic; the priests, the ecclesiastics, who officiated in sacred things; the Levites, who ministered to them; and the Nethinims were such persons as were "given", as the word signifies, to do servile work for the sanctuary, as, to be hewers of wood and drawers of water; such were the Gibeonites, Jos 9:27, and such as were appointed by David for such work, see Ezr 8:20.

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).
