Commentaries:
This young woman is full of the love for her husband, and her marriage is so satisfying that she feels complete freedom to initiate love. Her sexual desire has a free and lawful outlet to it. She is burning with desire to be with him, and that is the point. Solomon is writing here of the love of the church for Jesus Christ, and there is passion in those who are doing . . . what? She seeks to have experiences with Him! Nobody else matters. She desires Him.
