From that time forth began Jesus to show unto his disciples,.... From the time that Peter made the confession concerning Jesus, as that he was the Messiah, and Son of God, and which things were clear to all the apostles, he began to teach them more expressly, and to point out to them more clearly, and plainly, his sufferings and death, than he had done before: and this he chose to do now, partly because that their faith in him was well grounded and established, so that they were the better able to bear these things he told them, which before might have been more staggering and discouraging to them; and partly, that being forewarned of them, they would not be so shocking when they came to pass: as also to destroy all their expectations of a temporal kingdom, which they might now be big with, he having so fully and freely owned himself to be the Messiah: and this also furnishes out some reasons why Jesus would not have his disciples, for the present, declare him to be the Messiah, that his death might not, by any means, be prevented, which was so necessary; since, should the princes of the world know him, they would not crucify him: and besides, seeing he was to suffer, and die, and rise again for the salvation of his people, it was proper that all this should be over before he was so publicly declared to be the Messiah, the Saviour, and Redeemer.
How that he must go to Jerusalem: the metropolis of the nation, where the great sanhedrim sat, who only could take cognizance of him, under the imputation of a false prophet, and condemn him to death, and which therefore would be in the most public manner; and though it would add to his reproach, would leave no room to be doubted of.
