Matthew 3:6

3 For this is he that was spoken of by Isaias the prophet, saying: A voice of one crying in the desert, Prepare ye the way of the Lord, make straight his paths.

4 And the same John had his garment of camel's hair, and a leathern girdle about his loins: and his meat was locusts and wild honey.

5 Then went out to him Jerusalem and all Judea, and all the country about Jordan:

6 And were baptized by him in the Jordan, confessing their sins.

7 And seeing many of the Pharisees and Sadducees coming to his baptism, he said to them: Ye brood of vipers, who hath shewed you to flee from the wrath to come?

8 Bring forth therefore fruit worthy of penance.

9 And think not to say within yourselves, We have Abraham for our father. For I tell you that God is able of these stones to raise up children to Abraham.
