Luke 3:3, 21-22

And he went into all the region around the Jordan, proclaiming a baptism of repentance for the forgiveness of sins.

Now when all the people were baptized, and when Jesus also had been baptized and was praying, the heavens were opened, and the Holy Spirit descended on him in bodily form, like a dove; and a voice came from heaven, “You are my beloved Son; with you I am well pleased.”
