Shir HaShirim Rabbah 3:3/שיר השירים רבה ג׳:ג׳

1“The watchmen who patrol the city found me: Have you seen the one whom my soul loves?” (Song of Songs 3:3).“The watchmen who patrol,” this is the tribe of Levi, just as it says: “Pass back and forth from gate to gate” (Exodus 32:27). “The one whom my soul loves,” this is Moses.
