25:1 There is more to prophesying than predicting the future. Prophecy also involves singing God’s praises and preaching God’s messages (1 Corinthians 14:1ff). 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.
25:1-7 There were many ways to contribute to the worship in the Tabernacle. Some prophesied (25:1), some offered thanks and praise (25:3), and others played instruments and sang (25:6, 7). God wants all his people to participate in worship. You may not be a master musician, a prophet, or a teacher, but God appreciates whatever you have to offer. Develop your special gifts to offer in service to God (Romans 12:3-8; 1 Corinthians 12:29-31).
25:9-31 The musicians were divided into 24 groups to match the 24 groups of Levites (24:7-18). 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.
