Boyd’s Bible Dictionary:
(pull and push). A wind instrument, trombone. But in Dan. 3:5-15, a stringed instrument of triangular shape with from four to twenty strings.
Concise Bible Dictionary:
The Hebrew word sabka is judged to refer to a stringed musical instrument—not a wind instrument, as the name sackbut implies (Dan. 3:5-15). It was probably the same as the sambuca of the Greeks and Romans. This was a triangular harp.
