Acts 19:4 Meaning and Commentary

Acts 19:4

Then said Paul

which required repentance antecedent to it, and was a fruit and effect, and so an evidence of it:

saying unto the people;
the people of the Jews, the common people, the multitude that attended on his ministry:

that they should believe on him, which should come after him,
