Mark 10:32-34

They were in the way to Jerusalem, and Jesus went before them: and they were amazed At his courage and intrepidity, considering the treatment which he had himself told them he should meet with there: and as they followed, they were afraid Both for him and themselves: nevertheless, he judged it best to prepare them, by telling them more particularly what was to ensue. The rulers at Jerusalem had issued out a proclamation against our Lord, immediately after the resurrection of Lazarus, and probably promised a reward to any that would apprehend him, John 11:57. This might be the reason why the disciples were astonished at the alacrity which their Master showed in this journey to the capital city, and afraid while they followed him. In such circumstances our Lord knew that a repetition of the prophecy concerning his own sufferings was proper; because it showed the disciples they were entirely voluntary. And as he told them expressly that they had been predicted by the prophets, and consequently decreed of old by God, the opposition that he was to meet with, though it would end in death, instead of weakening their faith, ought to have increased it; especially as he informed them at the same time that he would rise again the third day. Behold we go up to Jerusalem, &c. See on Matthew 20:18.
