Matthew 3:10-12

10And now also the axe is laid to the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire. 11I indeed baptize you in water to repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you in the Holy Spirit, and in fire: 12Whose fan is in his hand, and he will thoroughly cleanse his floor, and gather his wheat into the barn; but he will burn the chaff with unquenchable fire.
