Psalm 92/Notes/Grammar.V. 1.361185
From Psalms: Layer by Layer
v. 1 – The alternative construct chain is represented by the genitive found in the LXX (Ψαλμὸς ᾠδῆς "A psalm of a song"), Symmachus (ᾆσμα ψαλμοῦ "a song of a psalm," from Syro-Hex. ܙܡܝܪܬܐ ܕܡܙܡܘܪܐ), and Jerome, both Gall. and Hebr. (Psalmus cantici "a psalm of a song"), which does not seem to be followed, however, by modern translations.
Targum Psalm's conjunction (שבחא ושירא) has not been represented as an alternative, though it is followed by the DHH ("Salmo y cántico para el sábado").
