Matthew 3:11-12

11“I baptize you with water for repentance, but the one who is coming after me is more powerful than I. I am not worthy to remove his sandals. He himself will baptize you with the Holy Spirit and fire.

12His winnowing shovel is in his hand, and he will clear his threshing floor and gather his wheat into the barn. But the chaff he will burn with fire that never goes out.”
