“They were on the road, going up to Jerusalem, and Jesus was walking ahead of them. They were astonished, but those who followed Him were afraid. Taking the Twelve aside again, He began to tell them the things that would happen to Him.” ‭‭Mark‬ ‭10:32‬ ‭HCSB‬‬

Any time Jesus was walking, teaching, or trying to get alone time there was a crowd. Here in Mark, we find that The disciples were astonished but the crowd was afraid. Other times the crowd was pressing against Jesus (Mark 5:31). There was a time where Jesus was teaching and the crowd was so close that He had to teach from Peter’s boat (Luke 5:1-3). The crowd had walked all night to beat Jesus to his next spot (Matthew 13:13-14). Very rarely was Jesus alone, but even having the crowd behind him, I think, Jesus was feeling alone. He knew what was getting ready to happen. So now, for the third time, He is telling His disciples.

“Then He began to teach them that the Son of Man must suffer many things and be rejected by the elders, the chief priests, and the scribes, be killed, and rise after three days. He was openly talking about this. So Peter took Him aside and began to rebuke Him.”

“Then they left that place and made their way through Galilee, but He did not want anyone to know it. For He was teaching His disciples and telling them, “The Son of Man is being betrayed into the hands of men. They will kill Him, and after He is killed, He will rise three days later.” But they did not understand this statement, and they were afraid to ask Him.”

“Listen! We are going up to Jerusalem. The Son of Man will be handed over to the chief priests and the scribes, and they will condemn Him to death. Then they will hand Him over to the Gentiles, and they will mock Him, spit on Him, flog Him, and kill Him, and He will rise after three days.”
