Matthew 3:11-12

I indeed baptise you with water to repentance, but he that comes after me is mightier than I, whose sandals I am not fit to bear; he shall baptise you with the Holy Spirit and fire; whose winnowing fan is in his hand, and he shall thoroughly purge his threshing-floor, and shall gather his wheat into the garner, but the chaff he will burn with fire unquenchable.
