"The material of this section of the Gospel is particularly important since the baptism of Jesus serves as the occasion of his special anointing by the Holy Spirit for the ministry that follows, but it is also Christologically significant in that his divine Sonship is confirmed and the non-triumphalist nature of the present phase of that Sonship is indicated ( Matthew 3:17 c and Matthew 4:1-11). Thus Matthew provides information that is vitally important to an understanding of the narrative that follows: what Jesus does in his ministry he does by the power of the Spirit; yet Jesus will not act in the manner of a triumphalist messiah, in accordance with popular expectation, but in his own unique way, in obedience to the will of his Father."

Matthew presented four witnesses to Jesus" messiahship in this section: John the Baptist ( Matthew 3:1-15), the Holy Spirit ( Matthew 3:16), the Father ( Matthew 3:17), and Satan ( Matthew 4:1-11). A fifth witness follows in Matthew 4:12-15, namely, Jesus" ministry. [source][source][source]
