New Defender's Study Bible Notes
8:6 as a seal. As the Shulamite continues her expressions of love, she concludes with a testimony of her undying love for the king. She herself would be an indelible seal upon both his heart and his arm. The fires of her love would be as unending as death itself.
8:7 cannot quench love. Not even the waters of a mighty flood could quench the fires of her love; it could never be extinguished. Neither could all the riches of a wealthy man purchase it. Such should be the love we have for Christ.
8:8 a little sister. Song of Solomon 8:8-9 seems to be a remembrance by the Shulamite of the determination of her older brothers (mentioned in Song of Solomon 1:6 as “my mother’s children” who “were angry with me”) to guide and protect her as she grew through puberty. If she should become like a “door,” open to any who sought to enter, they would restrict her. If she would be like a “wall,” they would encourage and help her (Song of Solomon 8:9). She proved, indeed, to be a “wall,” her breasts became “towers” (Song of Solomon 8:10); and she became King Solomon’s bride!
8:11 keepers. In these two verses, the bride explains how she came to meet the shepherd king in the first place. Solomon had leased some of his vineyards to her brothers and herself, and they worked them for twenty percent of the profits. She had not kept her own vineyard, however (Song of Solomon 1:6), going to marry Solomon instead.
8:12 My vineyard. Since she had not been able to care for her vineyard, she asked Solomon to turn it over to her brothers, in return for their caring for her when she was younger.
