Every girl in love has to have a cheerleading section, right? Who else will tell her how long to wait before returning a text? The Daughters of Jerusalem play this role—kind of—for the bride:
I adjure you, O daughters of Jerusalem,
if you find my beloved,
tell him this:
I am faint with love. (5:8)
It's like passing a note in junior high.
But these girls also serve as a point of comparison to the bride. They are maidens—unmarried women—and we learn in Chapter 6 that the bride surpasses all other maidens. So not only do they provide an entourage, they also showcase the bride as the best of the best.
