The poem consists of six four-line
stanzas with the rhyme-scheme a a a a, b b b b, c c c c, etc. The wording varies slightly between manuscripts. The first three verses make up the song proper; each is signed with the acrostic DUNaSH. Many manuscripts continue with verse 4 or verses 4-5, which are not signed. MS Giessen 742, Add MS 27200, NY JTS 8092, and BUD 370 include verses 1-5 and then continue directly into another poem in a similar metre beginning "אדום עקר", which also completes the poem in abbreviated form in MS Parma 1721. The final verse in prayerbooks and MS Bod. 1100 is grafted from another of Dunash's poems, beginning "דלה שובב" and found in MS 27200,
AIU H133, and some Geniza fragments. One Geniza fragment includes four stanzas of
Devai Haser, then verses 2,3,1, and 4 (in that order) of Dror Yikra, but these are properly separate piyyutim. ==Biblical references==
