Mark 10:32-38, 41-45

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, 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). 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].” James and John, the two sons of Zebedee, came to Him, saying, “Teacher, we want You to do for us whatever we ask of You.” [Matt 20:20, 21] And He replied to them, “What do you want Me to do for you?” They said to Him, “Grant that we may sit [with You], one on Your right and one on Your left, in Your glory [Your majesty and splendor in Your kingdom].” But Jesus said to them, “You do not know what you are asking. Are you able to drink the cup that I drink, or to be baptized with the baptism [of suffering and death] with which I am baptized?”

Hearing this, the [other] ten became indignant with James and John. Calling them to Himself, Jesus said to them, “You know that those who are recognized as rulers of the Gentiles lord it over them; and their powerful men exercise authority over them [tyrannizing them]. But this is not how it is among you; instead, whoever wishes to become great among you must be your servant, and whoever wishes to be first and most important among you must be slave of all. 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.”
