Mattithyahu (Matthew) 3:11-12

I indeed immerse you in water unto repentance, but He who is coming after me is mightier than I, whose sandals I am not worthy to bear. He shall immerse you in the Set-apart Spirit and fire. His winnowing fork is in His hand, and He shall thoroughly cleanse His threshing-floor, and gather His wheat into the storehouse, but the chaff He shall burn with unquenchable fire.
