Acts 19:4

Paul explained: “John’s baptism was a baptism of repentance. He told the people to believe in the One coming after him, that is, in Jesus.”

Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.

Paul said, “John indeed baptized with the baptism of repentance, saying to the people that they should believe in the one who would come after him, that is, in Christ Jesus.”

Note NU omits Christ.
