John Trapp on Song of Solomon 3:5

Verſ. 5. I charge you, O yee daughters of Jeruſalem] As a further fruit of her revived faith, ſhee renews her conteſtation, and charge of ſanctification of life, ſuch as becometh the Goſpel; that Chriſt whom ſhee reſolves now to retain with her, bee not provoked by ſin to leave his people, Numb. 32.15. And in this vehement adjuration, no doubt, ſaith an Interpreter, but the Church had a ſpecial regard to the cuſtome uſed then, and yet even at this day uſed amongſt us: namely, that ſongs are ſung before the Bride-chamber, and certain noiſes of Inſtruments brought to wake the Bride and Bridegroom from ſleep. See the Note on chap. 2.7.
