Now these are the divisions of the sons of Aaron,.... Into the classes or courses following: the sons of Aaron; Nadab and Abihu, Eleazar and Ithamar; Ch1 6:3, these were the immediate sons of Aaron; but the division or distribution of them into classes are of their posterity in the times of David, who descended from the two latter.

The particular account of these establishments is of little use to us now; but, when Ezra published it, it was of great use to direct their church affairs after their return from captivity into the old channel again. The title of this record we have v. 1 - These are the divisions of the sons of Aaron, not by which they divided one from another, or were at variance one with another (it is a pity there should ever be any such divisions among the sons of Israel, but especially among the sons of Aaron), but the distribution of them in order to the dividing of their work among themselves; it was a division which God made, and was made for him. 1. This distribution was made for the more regular discharge of the duties of their office. God was, and still is, the God of order, and not of confusion, particularly in the things of his worship. Number without order is but a clog and an occasion of tumult; but when every one has, and knows, and keeps, his place and work, the more the better. In the mystical body, every member has its use, for the good of the whole, Rom 12:4, Rom 12:5; Co1 12:12. 2. It was made by lot, that the disposal thereof might be of the Lord, and so all quarrels and contentions might be prevented, and no man could be charged with partiality, nor could any say that they had wrong done them. As God is the God or order, so he is the God of peace. Solomon says of the lot that it causeth contention to cease. 3. The lot was cast publicly, and with great solemnity, in the presence of the king, princes, and priests, that there might be no room for any fraudulent practices or the suspicion of them. The lot is an appeal to God, and ought to be managed with corresponding reverence and sincerity. Matthias was chosen to the apostleship by lot, with prayer (Act 1:24, Act 1:…

24:1-19 The information about the priests’ duties includes only their organization into orders and the assignment of their responsibilities by casting lots. The Chronicler does not explain their duties because they had long been solidly established (see Exod 28:1-5; Lev 1–7; Num 6:22-27). 24:1-2 The organization of the priests into their divisions for service began with Aaron’s sons Eleazar and Ithamar; all of Israel’s priests were descended from these two men.
