I Chronicles 24:7

Now the first lot came forth to Jehoiarib,.... And the other twenty three to the following persons in order: Jedaiah, Harim, Seorim, Malchijah, Mijamin, Hakkoz, Abijah, Jeshua, Shecaniah, Eliashib, Jakim, Huppah, Jeshebeab, Bilgah, Immer, Hezir, Aphses, Pethahiah, Jehezekel, Jachin, Gamul, Delaiah, and Maaziah; of all which courses we know little more than their names, though they continued in some form or other both under the first and second temple, to the destruction of it; the Jews say only four of these courses returned from the Babylonish captivity, which were those of Jedaiah, Harim, Pashur, and Immer; though Pashur is not among these here; yet they say each of these four had six lots, and that the names and the order of the other courses were retained and continued under them, and supplied by them: hence we read of Mattithiah, from whom sprung the Maccabees, as of the course of Jehoiarib,"In those days arose Mattathias the son of John, the son of Simeon, a priest of the sons of Joarib, from Jerusalem, and dwelt in Modin.'' (1 Maccabees 2:1)which was the first course, and the most honourable; wherefore Josephus (p), who was of it, valued himself upon it, that he was not only of the priestly order, but of the first class or course of the twenty four; and we also read of the course of Abijah, the eighth course, of which was Zechariah the father of John the Baptist, Luk 1:5 of these courses; see Gill on Luk 1:5. (p) Vita ejus, sect. 1.

This chapter gives us a more particular account of the distribution of the priests and Levites into their respective classes, for the more regular discharge of the duties of their offices, according to their families. I. Of the priests (v. 1-19). II. Of the Levites (Ch1 24:20-31).

24:7-18 The twenty-four divisions established for the priests continued unchanged for many generations; the order of Abijah (24:10) is specifically mentioned in Luke 1:5, 8.
