For even the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.
Matthew Henry
To convince them ... he sets before them his own example; "The Son of man submits first to the greatest hardships and hazards, and then enters into his glory, and can you expect to come to it any other way; or to have more ease and honour than he has?" (1) He takes upon him the form of a servant, comes not to be ministered to, and waited upon, but to minister, and wait to be gracious. (2) He comes obedient to death, and to its dominion, for he gives his life a ransom for many; did he die for the benefit of good people, and shall not we study to live for their benefit?
John Gill
For even the son of man,.... That is, Christ himself; a name by which he frequently goes both in the Old and New Testament to the arguments before produced, Christ adds his own example, to teach his disciples humility and lowliness of mind and to check their ambitious views and desires:
came not to be ministered unto not but that he was ministered unto even by the angels of God; who ministered to him in the wilderness, after he had been tempted by Satan; and he was also ministered unto by some women out of their substance; but these show the low estate he was in to stand in need of such ministrations: here the sense is that he did not appear as an earthly prince, with a fine equipage, a large retinue and attendance,
but to minister; to be a servant, as he is in his mediatorial office and capacity: he was sent, and came as the servant of the Lord; and he ministered, in his prophetic office, the Gospel unto men; and went about in the form of a servant, doing good, ministering medicine both to the souls end bodies of men: but the great work he came about, was the work of man's redemption; which he willingly and cheerfully undertook, diligently and faithfully prosecuted, and has completely finished; to which respect is had in the next clause:
and to give his life a ransom for many; even for all the elect of God, to redeem them from sin, Satan, and the law; and secure them from the wrath of God, and eternal death; and this he has done, by laying down his life as the ransom price for them; see Mt 20:28.
