Historically, in both Jewish and Christian literature, the Song of Solomon has more commentaries written on it than any other book in the Bible. This may be surprising to some. And the interpretation most commonly accepted is that of an allegory of the personal intimate relationship between God and the individual believer - even among some rabbinic literature. The second most common interpretation is that it is an allegory between God and the corporate body of believers - either Jewish or Christian depending on the author of course. However when one understands it through the lens of the individual’s relationship with God, it actually makes far better sense than the other various approaches.

“My lover is mine and I am his” Song of Songs 2:16

“Heaven forbid that any man in Israel ever disputed that the Song of Songs is holy. For the whole world is not worth the day on which the Song of Songs was given to Israel, for all the Writings are holy and the Song of Songs is the Holy of Holies. (Mishnah Yadayim 3:5).
