Song of Songs Rabbah 6:7

¹“Your temple is like a pomegranate slice behind your braid” (Song of Songs 6:7). “Your temple [ rakatekh ] is like a pomegranate slice.” At that moment, Moses began praising them: Even the empty among you is packed with mitzvot and good deeds like the pomegranate, for anyone who is confronted by the opportunity to commit a transgression and is spared from it and does not perform it has performed a great mitzva. It goes without saying: “Behind your braid [ letzamatekh ]” regarding the modest and the fervent [ metzumatin ] among you.
