1 Chronicles 24:5

Thus were they divided by lot That the business being committed, in this way, to the Divine disposal, there might be no occasion for complaint, and so all contentions might be prevented, as no man could be charged with partiality, nor could any say they had wrong done them. Solomon says, the lot causes contention to cease. It is evident from the Scriptures, that it was a very ancient custom to refer matters of a doubtful nature to the decision of the lot; and, in particular, persons were often chosen in this way to sacred offices. But, as it is an appeal to God, it ought to be managed with a proper reverence and sincerity. Thus Matthias was chosen to the apostleship by lot with solemn prayer. “And I know not,” says Henry, “but it might still be used, in faith, in parallel cases, as an instituted ordinance.” One sort with another Both the sons of Eleazar and those of Ithamar were thus chosen, who should wait together. Governors of the house of God Hebrew, governors of God; that is, the judges, says Houbigant. The ministers of religion are expressed in the foregoing words, the governors of the sanctuary. It is very justly observed by Grotius, that governors of God never signify, in the sacred writings, those that minister to God, but governors in the commonwealth, chiefs, or judges. Were of the sons of Eleazar and the sons of Ithamar These two families had obtained the chief functions, both in the temple and in the magistracy; which could not be distributed so well any way as by lot, without danger of envy among themselves.
