He who has the bride is the bridegroom; but the friend of the bridegroom, who stands and hears him, rejoices greatly because of the bridegroom's voice. This, my joy, therefore is made full.
The bride is probably a reference to Israel (cf. Isaiah 54:5; Isaiah 62:4-5; Jeremiah 2:2; Jeremiah 3:20; Ezekiel 16:8; Hosea 2:16-20). John was therefore implying that he played a supporting role in Messiah’s union with Israel. This was a testimony to Jesus’ identity as Messiah whom John said he rejoiced to hear.
