Observe, I. Singing the praises of God is here called prophesying (Ch1 25:1-3), not that all those who were employed in this service were honoured with the visions of God, or could foretel things to come. Heman indeed is said to be the king's seer in the words of God (Ch1 25:5); but the psalms they sang were composed by the prophets, and many of them were prophetical; and the edification of the church was intended in it, as well as the glory of God. In Samuel's time singing the praises of God went by the name of prophesying (Sa1 10:5; Sa1 19:20), and perhaps that is intended in what St. Paul calls prophesying, Co1 11:4; Co1 14:24.

II.This is here called a service, and the persons employed in it workmen, Ch1 25:1. Not but that it is the greatest liberty and pleasure to be employed in praising God: what is heaven but that? But it intimates that it is our duty to make a business of it, and stir up all that is within us to it; and that, in our present state of corruption and infirmity, it will not be done as it should be done without labour and struggle. We must take pains with our hearts to bring them, and keep them, to this work, and to engage all that is within us.

III.Here were, in compliance with the temper of that dispensation, a great variety of musical instruments used, harps, psalteries, cymbals (Ch1 25:1, Ch1 25:6), and here was one that lifted up the horn (Ch1 25:5), that is, used wind-music. The bringing of such concerts of music into the worship of God now is what none pretend to. But those who use such concerts for their own entertainment should feel themselves obliged to preserve them always free from any thing that savours of immorality or profaneness, by this consideration, that time was when they were sacred; and then those were justly condemned who brought them into common use, Amo 6:5. They invented to themselves instruments of music like David.

IV.The glory and honour of God were principally intended in all this temple-music, whether vocal or instrumental. It was to give thanks, and praise the Lord, that the singers were employed, Ch1 25:3. It was in the songs of the Lord that they were instructed (Ch1 25:7), that is, for songs in the house of the Lord, Ch1 25:6. This agrees with the intention of the perpetuating of psalmody in the gospel-church, which is to make melody with the heart, in conjunction with the voice, unto the Lord, Eph 5:19.

V.The order of the king is likewise taken notice of, Ch1 25:2 and again Ch1 25:6. In those matters indeed David acted as a prophet; but his taking care for the due and regular observance of divine institutions, both ancient and modern, is an example to all in authority to use their power for the promoting of religion, and the enforcing of the laws of Christ. Let them thus be ministers of God for good.

VI.The fathers presided in this service, Asaph, Heman, and Jeduthun (Ch1 25:1), and the children were under the hands of their father, Ch1 25:2, Ch1 25:3, Ch1 25:6. This gives a good example to parents to train up their children, and indeed to all seniors to instruct their juniors in the service of God, and particularly in praising him, than which there is no part of our work more necessary or more worthy to be transmitted to the succeeding generations. It gives also an example to the younger to submit themselves to the elder (whose experience and observation fit them for direction), and, as far as may be, to do what they do under their hand. It is probable that Heman, Asaph, and Jeduthun, were bred up under Samuel, and had their education in the schools of the prophets which he was the founder and president of; then they were pupils, now they came to be masters. Those that would be eminent must begin early, and take time to prepare themselves. This good work of singing God's praises Samuel revived, and set on foot, but lived not to see it brought to the perfection it appears in here. Solomon perfects what David began, so David perfects what Samuel began. Let all, in their day, do what they can for God and his church, though they cannot carry it so far as they would; when they are gone God can out of stones raise up others who shall build upon their foundation and bring forth the top-stone.

VII.There were others also, besides the sons of these three great men, who are called their brethren (probably because they had been wont to join with them in their private concerts), who were instructed in the songs of the Lord, and were cunning or well skilled therein, Ch1 25:7. They were all Levites and were in number 288. Now, 1. These were a good number, and a competent number to keep up the service in the house of God; for they were all skilful in the work to which they were called. When David the king was so much addicted to divine poesy and music many others, all that had a genius for it, applied their studies and endeavours that way. Those do religion a great deal of good service that bring the exercises of devotion into reputation. 2. Yet these were but a small number in comparison with the 4000 whom David appointed thus to praise the Lord, Ch1 23:5. Where were all the rest when only 288, and those but by twelve in a course, were separated to this service? It is probable that all the rest were divided into as many courses, and were to follow as these led. Or, perhaps, these were for songs in the house of the Lord (Ch1 25:6), with whom any that worshipped in the courts of that house might join; and the rest were disposed of, all the kingdom over, to preside in the country congregations, in this good work: for, though the sacrifices instituted by the hand of Moses might be offered but at one place, the psalms penned by David might be sung every where, Ti1 2:8.

Which prophesied - Sung hymns and prayed. But the Targum understands this of prophesying in the proper sense of the term; and therefore says, "Who prophesied by the Holy Spirit." Jarchi is of the same opinion and quotes the case of Elisha, Kg2 3:15; While the minstrel played, the hand of the Lord [i.e., the spirit of prophecy] was upon him.

Of the sons of Asaph,.... Who were separated, and by lot appointed, to the service of singers in the temple:

Zaccur, and Joseph, and Nethaniah, and Asarelah; called Jesharelah, Ch1 25:14, these had the third fourth, fifth, and seventh lots, Ch1 25:9,

under the hands of Asaph; under his instruction and authority:

which prophesied according to the order of the king; which Asaph composed psalms under the inspiration of the Spirit of God, and was ordered by King David to sing them, and by whose command they were inserted in the book of Psalms, where they now stand with his name to them.

according to the order of the king--Hebrew, "by the hands of the king," that is, "according to the king's order," under the personal superintendence of Asaph and his colleagues.

which prophesied--that is, in this connection, played with instruments. This metaphorical application of the term "prophecy" most probably originated in the practice of the prophets, who endeavored to rouse their prophetic spirit by the animating influence of music (see on Kg2 3:15). It is said that Asaph did this "according to David's order," because by royal appointment he officiated in the tabernacle on Zion (Ch1 16:37-41), while other leaders of the sacred music were stationed at Gibeon.
