John verily baptized - John did indeed baptize.
With the baptism of repentance - Having special reference to repentance, or as a profession that they did repent of their sins. See the notes on Matthew 3:6.
Saying unto the people - The design of his preaching was to tarn the people from their sins, and to prepare them for the coming of the Messiah. He therefore directed their attention principally to him that was to come, John 1:15, John 1:22-27.
That is, on Christ Jesus - These are the words of Paul, explaining what John taught. John taught them to believe in the Messiah, and Paul now showed them that the Messiah was Jesus of Nazareth. The argument of Paul is, that it was highly proper for them now to profess publicly that Saviour to whom John had borne such explicit testimony. “Jesus is the Messiah for whom John came to prepare the way; and as you have em braced John’s doctrine, you ought now publicly to acknowledge that Redeemer by baptism in his name.
