2 during the high priesthood of Annas and Caiaphas, the word of God came to John the son of Zechariah in the wilderness. 3 And he went into all the region around the Jordan, proclaiming a baptism of repentance for the forgiveness of sins. 4 As it is written in the book of the words of Isaiah the prophet,

  “The voice of one crying in the wilderness:
  ‘Prepare the way of the Lord,
    make his paths straight.
5   Every valley shall be filled,
    and every mountain and hill shall be made low,
  and the crooked shall become straight,
    and the rough places shall become level ways,
6   and all flesh shall see the salvation of God.’”
