The principal word used is nebel, and it is supposed to refer to some unknown form of stringed instrument used to accompany the voice. It is at times mentioned along with the harp (1 Sam. 10:5; Psa. 33:2; Psa. 144:9; Psa. 150:3). The same word is also translated VIOL (Isa. 5:12; Isa. 14:11; Amos 5:23; Amos 6:5). In Daniel 3:5-15 the word is pesanterin.
