Matthew 20:17-19
17 As Jesus was going up to Jerusalem, He took the twelve [disciples] aside, and along the way He said to them, 18 “Listen carefully: we are going up to Jerusalem; and the Son of Man will be handed over to the chief priests and scribes (Sanhedrin, Jewish High Court), and they will [judicially] condemn Him and sentence Him to death, 19 and will hand Him over to the Gentiles (Roman authorities) to be mocked and scourged and crucified, and He will be raised [to life] on the third day.”
Mark 10:32-34
32 Now they were on the road going up to Jerusalem, and Jesus was walking on ahead of them; and they were perplexed [at what Jesus had said], and those who were following were alarmed and afraid. And again He took the twelve [disciples] aside and began telling them what was going to happen to Him,
33 saying, “Listen very carefully: we are going up to Jerusalem, and the Son of Man will be betrayed and handed over to the chief priests and the scribes; and they will condemn Him to death and hand Him over to the Gentiles (Romans). 34 They will mock and ridicule Him and spit on Him, and whip (scourge) Him and kill Him, and three days later He will rise [from the dead].”
Luke 18:31-34
31 Then taking the twelve [disciples] aside, He said to them, “Listen carefully: we are going up to Jerusalem, and all things that have been written through the prophets about the Son of Man will be fulfilled and completed. 32 He will be betrayed and handed over to the Gentiles (Roman authorities), and will be mocked and ridiculed and insulted and abused and spit on, 33 and after they have scourged Him, they will kill Him; and on the third day He will rise [from the dead].”
34 But the disciples understood none of these things [about the approaching death and resurrection of Jesus]. This statement was hidden from them, and they did not grasp the [meaning of the] things that were said [by Jesus].
