Verses 1–7
Chief Singers and Musicians, 1 Chronicles 25:1-7
These verses set forth the chief families of the Levites who were devoted to the service of song and music in the temple. It is unclear why the captains of the host are mentioned in connection with their separation. Three chief men were set apart to this work; Asaph, Jeduthun, and Heman. Asaph was head of the choir, and some twelve of the Psalms are titled to him, or his sons. This may mean that they were prepared for his choral use, or he may have been the author of some of them. There were four sons of Asaph over the remainder of his family. They were of the Levitical family of Gershon.
Jeduthun was of the Levitical family of Merari. Some think he is the same person called Ethan in other places. He and his family assisted the Asaphites in the choir, and played on the harp also. Jeduthun had six sons who were over other members of the family.
Heman was of a very prominent. family in Israel, the son of Joel and grandson of the prophet Samuel. His family composed the orchestra, and provided most of the musical instrumentation in the temple worship. His was also the largest family of the three, being fourteen sons and three daughters. It seems the daughters may also have been included among the musicians. They represented the Levitical family of Kohath. Heman is called the king’s seer, which means that he received revelations from the Lord for the king and conveyed them to him. To "lift up the horn" means that he exalted the word of God to the king.
It is said that these men all ’prophesied" with their songs and instruments of music. Many times in the Old Testament the word "prophesy" is used in about the same sense as "preach" is used today. All singing and music should exalt the Lord and extol His word, and that is just what these people did so long ago. Their service was for the Lord and advanced His name and cause in Israel.
The chief musicians then, were three: Asaph, with four sons under his hand; Jeduthun, with six sons under him; Heman, with fourteen sons (and possibly three daughters over the ladies of the choir). Under all these were many other singers and musicians to the total number of two hundred and eighty-eight. What a wonderful medley of voice they must have rendered in praise of the Lord! (Ephesians 5:18-21; Colossians 3:16).
