Matthew 3:1-2, 4-12

In those days came John the Baptist, preaching in the wilderness of Judæa, and saying, Repent ye: for the kingdom of heaven is at hand.

And the same John had his raiment of camel's hair, and a leathern girdle about his loins; and his meat was locusts and wild honey. Then went out to him Jerusalem, and all Judæa, and all the region round about Jordan, and were baptized of him in Jordan, confessing their sins. But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come? Bring forth therefore fruits meet for repentance: and think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham. And now also the axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire. I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire: whose fan is in his hand, and he will throughly purge his floor, and gather his wheat into the garner; but he will burn up the chaff with unquenchable fire.
