And as the people were in expectation, and all men questioned in their hearts concerning John, whether he was the Christ, or not; John answered, saying unto them all, I indeed baptize you with water; but one mightier than I comes, the thong of whose shoes I am not worthy to untie: he shall baptize you with the Holy Spirit and with fire: Whose fan is in his hand, and he will thoroughly purge his floor, and will gather the wheat into his garner; but the chaff he will burn with fire unquenchable. And many other things in his exhortation preached he unto the people. (Luke 3:15-18)
