Baptism of Jesus

Mark 1:9 And it came to pass in those days, that Jesus came from Nazareth of Galilee, and was baptized of John in Jordan. Matt 3:13 Then cometh Jesus from Galilee to Jordan unto John, to be baptized of him. 14 But John forbad him, saying, I have need to be baptized of thee, and comest thou to me? 15 And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Then he suffered him. Luke 3:2121a Now when all the people were baptized, it came to pass, that Jesus also being baptized, and praying [1], John 1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world. 30 This is he of whom I said, After me cometh a man which is preferred before me: for he was before me. 31 And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water.
Mark 1:10 And straightway coming up out of the water, he saw the heavens opened, and the Spirit like a dove descending upon him [2]: Matt 3:16 And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him: Luke 3:21b the heaven was opened, 22a And the Holy Ghost descended in a bodily shape like a dove upon him,
Mark 1:11 And there came a voice from heaven, saying, Thou art my beloved Son [3], in whom I am well pleased. [4], [5] Matt 3:17 And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased [6]. Luke 3:22b and a voice came from heaven, which said, Thou art my beloved Son; in thee I am well pleased.

John 1:32 And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him. 33 And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost. 34 And I saw, and bare record that this is the Son of God.

[1]Jesus is depicted as praying frequently in Mark (1:35, 6:46, 14:23, 14:32-39, 26:36-44) and Luke (3:21, 5:16, 6:12, 9:18, 9:28-29, 11:1, 22:41-46); once in Matthew (26:39-46); and not at all in John.

[2]In Mark only Jesus sees this; Matthew is ambiguous; Luke implies that it could have been seen by all.

[3]God also says "This is my beloved son" in Mark 9:7.

[4]Isaiah 42:1 Behold my servant, whom I uphold; mine elect, in whom my soul delighteth; I have put my spirit upon him: he shall bring forth judgment to the Gentiles. This is a description of a servant who is to come. Isaiah does not make clear whether this servant is a nation or an individual (New Oxford Annotated Bible, p. 1213)

[5]John couldn't have heard God's words or seen the Spirit descend on Jesus, because he later expresses doubts about Jesus' divinity (Matthew 11:3, and Luke 7:19 for example).

[6]God repeats these words in Matthew 17:5.
