John 1:23-29
English Standard Version
24(Now they had been sent from the Pharisees.)
25They asked him, "Then why are you baptizing, if you are neither the Christ, nor Elijah, nor the Prophet?"
26John answered them, "I baptize with water, but among you stands one you do not know,
27even he who comes after me, the strap of whose sandal I am not worthy to untie."
28These things took place in Bethany across the Jordan, where John was baptizing.
