Luke 3:15-17, 21-22

And as the people were in expectation, and all men reasoned in their hearts concerning John, whether haply he were the Christ; John answered, saying unto them all, I indeed baptize you with water; but there cometh he that is mightier than I, the latchet of whose shoes I am not worthy to unloose: he shall baptize you in the Holy Spirit and in fire: whose fan is in his hand, thoroughly to cleanse his threshing-floor, and to gather the wheat into his garner; but the chaff he will burn up with unquenchable fire.

Now it came to pass, when all the people were baptized, that, Jesus also having been baptized, and praying, the heaven was opened, and the Holy Spirit descended in a bodily form, as a dove, upon him, and a voice came out of heaven, Thou art my beloved Son; in thee I am well pleased.
