The one having the Kallah (bride) is the Choson (Bridegroom, i.e., Rebbe, Melech HaMoshiach) but the Shoshvin (the Choson's best man), the one having stood and hearing him with simcha, rejoices because of the kol (voice) of the Choson (Bridegroom). Therefore, this simcha of mine has been made sheleimah (complete).
