Jeduthun

lauder; praising, a Levite of the family of Merari, and one of
the three masters of music appointed by David (1 Chr. 16:41, 42;
25:1-6). He is called in 2 Chr. 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 (1 Chr. 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.
