21 Now when all the people were baptized, and when Jesus also had been baptized and was praying, the heavens were opened,22 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.”
Mark 1
9 In those days Jesus came from Nazareth of Galilee and was baptized by John in the Jordan.10 And when he came up out of the water, immediately he saw the heavens being torn open and the Spirit descending on him like a dove.11 And a voice came from heaven, “You are my beloved Son; with you I am well pleased.”
Matthew 3
13 Then Jesus came from Galilee to the Jordan to John, to be baptized by him.14 John would have prevented him, saying, “I need to be baptized by you, and do you come to me?”15 But Jesus answered him, “Let it be so now, for thus it is fitting for us to fulfill all righteousness.” Then he consented.16 And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him;17 and behold, a voice from heaven said, “This is my beloved Son, with whom I am well pleased.”
