I read that Adam, Malki Zedek, Abraham, Moses, Heiman, Jeduthun, Asaph, and the three sons of Korach along with David wrote the Psalm, the Eastern Orthodox believe Moses, David and Temple musicians. Who wrote the Psalms? Gill : The Jews make mention of ten, which are differently reckoned by them. According to Jarchi (d), they were Adam, Melchizedek, Abraham, Moses, David, Solomon, Asaph, and the three sons of Korah. According to Kimchi (e), they were Adam, the first, Melchizedek, Abraham, Asaph, Heman, Jeduthun, Moses, and the three sons of Korah; Asir, Elkanah, and Abiasaph. Some ascribe all the Psalms to David (f), and think that those which are said to be a psalm of Asaph, or of Heman, &c. should be rendered "a psalm to Asaph", &c. and only signify that they were psalms delivered to them, to be sung in a public manner.
