Luke 3:3, 21-22

And he came into all the country about Jordan, preaching the baptism of repentance for the remission of sins

Now when all the people were baptized, it came to pass, that Jesus also being baptized, and praying, the heaven was opened, and the Holy Ghost descended in a bodily shape like a dove upon him, and a voice came from heaven, which said, Thou art my beloved Son; in thee I am well pleased.
