Most of the Levites here named were mentioned before, 1 Chron. 23:16-23 They were of those who were to attend the priests in the service of the house of God. But they are here mentioned again as heads of the twenty-four courses of Levites (and about so many are here named), who were to attend the twenty-four courses of the priests: they are therefore said to cast lots over against their brethren (so they are called, not their lords), the sons of Aaron, who were not to lord it over God’s clergy, as the original word is, 1 Pet. 5:3. And, that the whole disposal of the affair might be of the Lord, the principal fathers cast lots over against their younger brethren; that is, those that were of the elder house came upon he level with those of the younger families, and took their place, not by seniority, but as God by the lot directed. Note, In Christ no difference is made between bond and free, elder and younger. The younger brethren, if they be faithful and sincere, shall be no less acceptable to Christ than the principal fathers.
