Matthew 3:11-12

I baptize you with water to show that you have repented, but the one who will come after me will baptize you with the Holy Spirit and fire. He is much greater than I am; and I am not good enough even to carry his sandals. He has his winnowing shovel with him to thresh out all the grain. He will gather his wheat into his barn, but he will burn the chaff in a fire that never goes out.”
