Song of Songs Rabbah 4:3

¹“Your lips are like a scarlet thread, and your speech is lovely; your temple is like a pomegranate slice behind your braid” (Song of Songs 4:3). “Your lips are like a scarlet thread” – when they sang the song: “Then sang Moses [and the children of Israel]” (Exodus 15:1). “Your speech is lovely [ naveh ]” – that they point with their finger and say: “This is my God and I will glorify Him [ ve’anvehu ]” (Exodus 15:2). At that moment, Moses began praising them: “Your temple [ rakatekh ] is like a pomegranate slice” – even the empty [ hareikan ] among you is packed with mitzvot like this pomegranate. It goes without saying: “Behind your braid [ letzamatekh ]” – regarding the modest and the fervent [ metzumatin ] among you.
