От Матфея 3:6

And were baptized of him in Jordan, confessing their sins--probably confessing aloud. This baptism was at once a public seal of their felt need of deliverance from sin, of their expectation of the coming Deliverer, and of their readiness to welcome Him when He appeared. The baptism itself startled, and was intended to startle, them. They were familiar enough with the baptism of proselytes from heathenism; but this baptism of Jews themselves was quite new and strange to them.

At the start of this chapter, concerning the baptism of John, begins the gospel (Mar 1:1); what went before is but preface or introduction; this is "the beginning of the gospel of Jesus Christ." And Peter observes the same date, Act 1:22, beginning from the baptism of John, for then Christ began first to appear in him, and then to appear to him, and by him to the world. Here is, I. The glorious rising of the morning-star - John the Baptist (Mat 3:1). 1. The doctrine he preached (Mat 3:2). 2. The fulfilling of the scripture in him (Mat 3:3). 3. His manner of life (Mat 3:4). 4. The resort of multitudes to him, and their submission to his baptism (Mat 3:5, Mat 3:6). 5. His sermon that he preached to the Pharisees and Sadducees, wherein he endeavours to bring them to repentance (Mat 3:7-10), and so to bring them to Christ (Mat 3:11, Mat 3:12). II. The more glorious shining forth of the Sun of righteousness, immediately after: where we have, 1. The honour done by him to the baptism of John (Mat 3:13-15). 2. The honour done to him by the descent of the Spirit upon him, and a voice from heaven (Mat 3:16, Mat 3:17).
