The song

Also known as the Song of Solomon, a section of the Bible that is decidedly one of the most erotic, sensuous works of poetry that anybody can find. It's one of the "scrolls" (megillot) of the Writings (Ketuvim), the last section of the Hebrew Bible. It is also the fifth book of Wisdom in the Old Testament of the Christian Bible. The whole structure and plot is that of a pair of lovers from courtship to marriage to consummation is a celebration of erotic love. While it can be argued that it's a metaphor for the union between Yahweh and the land of Israel (or that between Christ and the Church), it's just as likely very seductive romantic poetry.
