A commentary on the Song of Songs, treating each verse at three levels: at the literal level, citing contemporary grammarians to explain every word on the scroll; at a rabbinical level, based on midrashic texts, symbolising the people of Israel's relationship with God; and at an allegorical level, describing the soul trying to unite itself with the intellect, supported by Jewish and Arab poets, and the philosophy of Al-Farabi and Avicenna.
