The Song of Songs, also known as the Song of Solomon or Canticles , is one of the megillot of the Ketuvim , and the fifth of the "wisdom" books of the Christian Old Testament.Scripturally, the Song of Songs is unique in that it makes no reference to "Law", "Covenant" or to Yahweh, the God of Israel, nor does it teach or explore "wisdom" in the manner of Proverbs or Ecclesiastes . Instead, it celebrates sexual love. It gives "the voices of two lovers, praising each other, yearning for each other, proffering invitations to enjoy". The two are in harmony, each desiring the other and rejoicing in sexual intimacy; the women of Jerusalem form a chorus to the lovers, functioning as an audience whose participation in the lovers' erotic encounters facilitates the participation of the reader.In modern Judaism, the Song is read on the Sabbath during the Passover, which marks the beginning of the grain harvest as well as commemorating the Exodus from Egypt. Jewish tradition reads it as an allegory of the relationship between God and Israel. Christian tradition, in addition to appreciating the literal meaning of a romantic song between man and woman, has read the poem as an allegory of Christ and his Church .
