The work was first edited by Theodor Rättig, Vienna in 1886, together with three other graduals: Locus iste, Christus factus est and Virga Jesse. In this first edition, something went wrong: the motet and the first Alleluja were issued, but not the extra verse (Inveni David) and the repeat of the Alleluja. The extra verse and the repeat of the Alleluja were wrongly classified by Grasberger as a separate work (Inveni David, WAB 20).
