14 Soldiers also asked him, "And we, what should we do?" He said to them, "Do not extort money from anyone by threats or false accusation, and be satisfied with your wages."
15 As the people were filled with expectation, and all were questioning in their hearts concerning John, whether he might be the Messiah,
16 John answered all of them by saying, "I baptize you with water; but one who is more powerful than I is coming; I am not worthy to untie the thong of his sandals. He will baptize you with the Holy Spirit and fire.
17 His winnowing fork is in his hand, to clear his threshing floor and to gather the wheat into his granary; but the chaff he will burn with unquenchable fire."
18 So, with many other exhortations, he proclaimed the good news to the people.
