1 Chronicles 25:2-3

2From Asaph's sons, there were: Zaccur, Joseph, Nethaniah and Asarelah. Asaph had authority over their work. He would speak a message from God when the king told him to do that.

3From Jeduthun's sons, there were six musicians: Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah and Mattithiah. Their father Jeduthun had authority over their work. He spoke messages from God while he made music with a harp. He also sang to thank the Lord and to praise him.
