I Chronicles 9:3

And in Jerusalem dwelt of the children of Judah, and of the children of Benjamin,.... Of which tribes were the largest number that went into, and returned out of, captivity: and of the children of Ephraim and Manasseh; such of those tribes who had joined the others when Jeroboam introduced his idolatry, or had fled to them when Samaria was besieged and taken by Shalmaneser, and so went into captivity with Judah, and now returned; and as many of them as took the advantage of the proclamation of Cyrus, who were carried captive with the ten tribes.

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).

9:3-9 settled in Jerusalem: Jerusalem had always been at the center of all Israel, and people from all the tribes lived there, both before and after the Exile. This statement affirms the inclusion of some members of the northern tribes among those who returned from exile.
