Of Jeduthun: the sons of Jeduthun; Gedaliah, and Zeri, and Jeshaiah, Shemei, Hashabiah, and Mattithiah, six, under the hands of their father Jeduthun, who prophesied with a harp, to give thanks and to praise the LORD.
All these were under the direction of their father in the music in the house of the LORD, with cymbals, lyres, and harps, for the service of the house of God, according to the king’s order to Asaph, Jeduthun, and Heman.
[To the Chief Musician. To Jeduthun. A Psalm of David.] I said, I will take heed to my ways, that I sin not with my tongue: I will keep my mouth with a bridle, while the wicked are before me.
