Muth-labben

MUTHLABBEN (mŭth'lăb'ĕn). An expression of uncertain meaning, occurring only in the title of Ps.9.1-Ps.9.20 (kjv, mlb, nasb, rsv). Probably it indicates the name of the tune (niv; cf. Christian hymnals) or the instruments of accompaniment (jb) to which the psalm was sung.

International Standard Bible Encyclopedia (1915)

(muth labben, "death of Ben," or "of the son"; Ps 9, title).
