Acts 19:4-8

4 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.

5 When they heard this, they were baptized in the name of the Lord Jesus.

6 And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.

7 And all the men were about twelve.

8 And he went into the synagogue, and spake boldly for the space of three months, disputing and persuading the things concerning the kingdom of God.
