'Baptism' in the Bible

beginning from his baptism by John until the day he was taken up from us -- one of these must become a witness of his resurrection together with us."

you know what happened throughout Judea, beginning from Galilee after the baptism that John announced:

Before Jesus arrived, John had proclaimed a baptism for repentance to all the people of Israel.

He had been instructed in the way of the Lord, and with great enthusiasm he spoke and taught accurately the facts about Jesus, although he knew only the baptism of John.

So Paul said, "Into what then were you baptized?" "Into John's baptism," they replied.

Paul said, "John baptized with a baptism of repentance, telling the people to believe in the one who was to come after him, that is, in Jesus."
