David and the temple officials chose the descendants of Asaph, Heman, and Jeduthun to be in charge of music. They were to praise the LORD by playing cymbals, harps and other stringed instruments. Here is a list of the musicians and their duties:
Jeduthun's six sons, Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah, were under the direction of their father and played harps and sang praises to the LORD.
But those who trust the LORD will find new strength. They will be strong like eagles soaring upward on wings; they will walk and run without getting tired.
