The TEV's introduction to this book of the Bible explains the context as follows:

The Song of Songs is a series of love poems, for the most part in the form of songs addressed by a man to a woman, and by the woman to the man. In some translations, the book is called The Song of Solomon, because it is attributed to Solomon in the Hebrew title. These songs have often been interpreted by Jews as a picture of the relationship between God and his people, and by Christians as a picture of the relationship between Christ and the Church.
