For this is he who was spoken of by the prophet Isaiah when he said, "The voice of one crying in the wilderness: Prepare the way of the Lord, make his paths straight."   Now John wore a garment of camel's hair, and a leather girdle around his waist; and his food was locusts and wild honey. Then went out to him, from Jerusalem and all Judea and all the region about the Jordan, and they were baptized by him in the river Jordan, confessing their sins.

But when he saw many of the Pharisees and Sadducees coming for baptism, he said to them, "You brood of vipers! Who warned you to flee from the wrath to come? Bear fruit that befits repentance,   and do not presume to say to yourselves, 'We have Abraham as our father'; for I tell you, God is able from these stones to raise up children to Abraham.
