Matthew 3:5-6, 11

Then Jerusalem was going out to him, and all Judea and all the district around the Jordan; and they were being baptized by him in the Jordan River, as they confessed their sins.

“As for me, I baptize you with water for repentance, but He who is coming after me is mightier than I, and I am not fit to remove His sandals; He will baptize you with the Holy Spirit and fire.
