John 1:23-27

²³“I,” he answered, “am — ‘The voice of one crying aloud in the wilderness: make a straight road for the Lord’, as the prophet Isaiah said.”

²⁴These men had been sent from the Pharisees;

²⁵and their next question was, “Why then do you baptize, if you are not the Christ or Elijah or ‘the prophet’?”

²⁶John's answer was — “I baptize with water, but among you stands one whom you do not know;

²⁷he is coming after me, yet I am not worthy even to unfasten his sandal.”
