lauder; praising, a Levite of the family of Merari, and one of the three masters of music appointed by David (1Ch 16:41,42; 25:1-6). He is called in 2Ch 35:15 "the king's seer." His descendants are mentioned as singers and players on instruments (Neh 11:17). He was probably the same as Ethan (1Ch 15:17,19). In the superscriptions to Ps. 39, 62, and 77, the words "upon Jeduthun" probably denote a musical instrument; or they may denote the style or tune invented or introduced by Jeduthun, or that the psalm was to be sung by his choir.
