'Baptism of Repentance' in the Bible

John the Baptizer appeared in the wilderness, preaching a baptism of repentance for the remission of sins.

And he came into all the country about the Jordan, preaching the baptism of repentance for the remission of sins;

before whose coming forward John had first preached a baptism of repentance to all the people of Israel.

Then said Paul, John indeed baptized with the baptism of repentance, saying to the people, that they should believe on him that was coming after him; that is, on Jesus.
