Luke 3:15-17

¹⁵ And as the people were in expectation, and all men mused in their hearts of John, whether he were the Christ, or not;

¹⁶ John answered, saying unto them all, I indeed baptize you with water; but one mightier than I cometh, the latchet of whose shoes I am not worthy to unloose: he shall baptize you with the Holy Ghost and with fire:

¹⁷ Whose fan is in his hand, and he will throughly purge his floor, and will gather the wheat into his garner; but the chaff he will burn with fire unquenchable.
