Luke 3:15-17  (New International Version)

 15The people were waiting expectantly and were all wondering in their hearts if John might possibly be the Christ.[a] 16John answered them all, "I baptize you with[b] water. But one more powerful than I will come, the thongs of whose sandals I am not worthy to untie. He will baptize you with the Holy Spirit and with fire. 17His winnowing fork is in his hand to clear his threshing floor and to gather the wheat into his barn, but he will burn up the chaff with unquenchable fire."

Luke 3:21-22

The Baptism and Genealogy of Jesus
  21When all the people were being baptized, Jesus was baptized too. And as he was praying, heaven was opened 22and the Holy Spirit descended on him in bodily form like a dove. And a voice came from heaven: "You are my Son, whom I love; with you I am well pleased."
