Shoshan'nim. (lilies). "To the chief musician upon Shoshannim" is a musical direction, to the leader of the Temple choir, which occurs in Psalms 45:1; Psalms 69:1, and most probably, indicates the melody "after" or "in the manner of" (Authorized Version, upon"), which the psalms were to be sung.

Shoshannim-eduth occurs, in the same way, in the title of Psalms 80:1. As the words now stand, they signify "lilies, a testimony", and the two are separated, by a large distinctive accent. In themselves, they have no meaning in the present text, and must, therefore, be regarded as, probably, a fragment of the beginning, of an older psalm, with which the choir were familiar.
