Matthew 3:15 (KJV)

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.

Then cometh Jesus from Galilee to Jordan unto John, to be baptized of him.

But John forbad him, saying, I have need to be baptized of thee, and comest thou to me?

And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him:

And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.
