Shiggaion shi-ga'-yon, shi-gi'-on (shiggayon): Occurs in the title of Psalms 7:1, and, in the plural, in the verse introducing Habakkuk's prayer (Habakkuk 3:1). Derived from a verb meaning "to wander," it is generally taken to mean a dithyramb, or rhapsody. This is not supported by the Greek VSS, but they are evidently quite at a loss.
