Song of Solomon 1:1 - Ellicott's Commentary On The Whole Bible

Song of Solomon 1:1 contains the title of the book: literally, A song of the songs (Heb., Shîr hashîrîm), which to Solomon, i.e., of which Solomon is author. This has been understood as meaning “one of Solomon’s songs,” with allusion to the 1,005 songs (1 Kings 4:32) which that monarch composed. But when in Hebrew a compound idea is to be expressed definitely, the article is prefixed to the word in the genitive. So here not merely “a song of songs” (comp. holy of holies), i.e., “a very excellent song,” but “The song of songs,” i.e., the most excellent or surpassing song. For the question of authorship and date of poem, see Excursus I.
