These likewise cast {f} lots over against their brethren the sons of Aaron in the presence of David the king, and Zadok, and Ahimelech, and the chief of the fathers of the priests and Levites, even the principal fathers over against their younger brethren.

(f) That is, every one had that honour which fell to him by lot.

Wesley's Notes

24:31 Over against - Answerable for number and order to those of the priests, so that there should be a course of the Levites for each course of the priests.

Matthew Henry's Concise Commentary

24:1-31 The divisions of the priests and Levites. - When every one has, knows, and keeps his place and work, the more there are the better. In the mystical body of Christ, every member has its use, for the good of the whole. Christ is High Priest over the house of God, to whom all believers, being made priests, are to be in subjection. In Christ, no difference is made between bond and free, elder and younger. The younger brethren, if faithful and sincere, shall be no less acceptable to Christ than the fathers. May we all be children of the Lord, fitted to sing his praises for ever in his temple above.

Matthew Henry's Whole Bible Commentary

Verses 20-31

Most of the Levites here named were mentioned before, ch. 23:16, etc. 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 Pt. 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.
