Luke 3:16-18

John answered them all by saying, I baptize you with water; but He Who is mightier than I is coming, the strap of Whose sandals I am not fit to unfasten. He will baptize you with the Holy Spirit and with fire. His winnowing shovel (fork) is in His hand to thoroughly clear and cleanse His [threshing] floor and to gather the wheat and store it in His granary, but the chaff He will burn with fire that cannot be extinguished. So with many other [various] appeals and admonitions he preached the good news (the Gospel) to the people.
