The young woman now speaks. It may have been that her breasts were once not fully developed, and she was just part of her brothers plans. But she is now a wall that has been breached as a matter of her free choice. She has no need any longer for their ornamental silver towers for she has towers of her own—her mature breasts. These towers are by no means defensive fortifications, but they actually draw her lover into her city.1
The woman has kept her virginity without the help of her brothers, until she met her husband. True love, as described in Song of Solomon 8:5–7, is by its very nature chaste: it is single-hearted in its lifelong commitment to one individual.2
10 I was a wall, and my breasts were like towers; then I was in his eyes as one who finds peace.
