A musical instrument, supposed to have been a kind of lyre, or a harp with twelve strings. The Hebrew word nebhel, so rendered, is translated “viol” in Isa. 5:12 (R.V., “lute”); 14:11. In Dan. 3:5, 7, 10, 15, the word thus rendered is Chaldaic, pesanterin, which is supposed to be a word of Greek origin denoting an instrument of the harp kind.
Psaltery
Whenever the music of worship is described, a psaltery is somewhere among the instruments. It was a stringed instrument, set beside the harp in nearly every mention: “Awake, psaltery and harp.” David and all Israel played “before the LORD,” and the Levites were stationed in the house with “cymbals, with psalteries, and with harps.” The psalmists name it too, singing to God on “an instrument of ten strings.” The picture is of music offered gladly and with all one’s might. Psalm 150 gathers the instruments together, and verse 3 names this one.
