I Chronicles 9:28

And other of their brethren, of the sons of the Kohathites, were over the shewbread, to prepare it every sabbath,.... Twelve loaves of which were set every week before the ark upon the shewbread table, and the old ones taken away: now the work of these Levites was to make this shewbread, and get it ready every week to be set upon the table, and which was done not by them, but by priests; under the second temple, the family of Garmu was set over this work (a). (a) Misn. Shekalim, ut supra. (c. 5. sect. 1.)

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).
