David and the army commanders then appointed men from the families of Asaph, Heman, and Jeduthun to proclaim God’s messages to the accompaniment of lyres, harps, and cymbals. Here is a list of their names and their work:
All these men were under the direction of their fathers as they made music at the house of the Lord. Their responsibilities included the playing of cymbals, harps, and lyres at the house of God. Asaph, Jeduthun, and Heman reported directly to the king. They and their families were all trained in making music before the Lord, and each of them—288 in all—was an accomplished musician. The musicians were appointed to their term of service by means of sacred lots, without regard to whether they were young or old, teacher or student.
(1 Chronicles 25:1, 6-8)
There is more to prophesying than predicting the future. Prophecy also involves singing God’s praises and preaching God’s messages (1 Corinthians 14). Prophets could be musicians, farmers (Amos 1:1), wives (2 Kings 22:14), or leaders (Deuteronomy 34:10)—anyone who boldly and accurately spoke out for God and tried to bring people back to worshiping him. From a large group of musicians David chose those who showed an unusual ability to tell about God and to encourage others in song.
It is fitting that David, a skilled musician, would take great interest in the organization of the musicians. The musicians were divided into twenty-four groups to match the twenty-four groups of Levites (1 Chronicles 24:7-25). This division of labor gave order to the planning of temple work, promoted excellence by making training easier, gave variety to worship because each group worked a term, and provided opportunities for many to be involved.
The fact that David consulted the commanders of the army also is fitting. During many battles, the priests carried the Ark or blew trumpets.
God wants all his people to participate in worship. He also wants his people to avoid envying the gifts of others, but to instead be content. You may not be a master musician, a prophet, or a teacher, but God appreciates whatever you have to offer. Develop your special gifts so you can offer them in service to God (Romans 12:3-8; 1 Corinthians 12:29-31).
