I Chronicles 9:30

These chief fathers of the Levites were chief throughout their generations,.... Even all before made mention of in this chapter: these dwelt at Jerusalem; always resided there, and did not in turns go into the country villages, as the inferior Levites did; their office requiring them to be constantly there, being chief of the porters, singers, &c. who had the superintendency and direction of the rest.

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).

9:30 The priests . . . blended the spices for use in the Tabernacle and Temple, and that blend could not be used for secular purposes (Exod 30:34-38).
