Mas'chil (Heb. maskil', מִשׂכַיל, instrlucting, Hiph. part. of שָׂכִל, to be wise; used as a noun in Ps 47:7, זִמּווּ מִשׂכַיל, sing ye a poem, Peshito, sing praise, but the Sept.,Vulg., and Auth.Vers. "sing ye with understanding") occurs in the titles or inscriptions of Ps 32; Ps 42; Ps 44; Ps 45; Ps 52; Ps 53; Ps 54; Ps 55; Ps 74; Ps 78; Ps 88; Ps 89; Ps 142. The origin of the use of this word is uncertain, and it has been variously interpreted. The most probable meaning of maschil is a poem, song, which enforces intelligence, wisdom, piety, q. d. didactic; which is true of every sacred song, not excepting Psalm 45, where everything is referred to the goodness of God. It occurs elsewhere as an adjective, and is accordingly rendered "wise," or some other term equivalent to instruction (1Sa 18:14-15; 2Ch 30:22; Job 22:2; Ps 14:2; Ps 41:1; Ps 53:2; Pr 10:5,19; Pr 14:35; Pr 15:24; Pr 16:20; Pr 17:2; Pr 19:14; Pr 21:12; Jer 1:9; Da 1:4; Da 11:33,35; Da 12:3,10; Am 5:13).
