Mark 10:35-41 NIV

[35] Then James and John, the sons of Zebedee, came to him. “Teacher,” they said, “we want you to do for us whatever we ask.” [36] “What do you want me to do for you?” he asked. [37] They replied, “Let one of us sit at your right and the other at your left in your glory.” [38] “You don’t know what you are asking,” Jesus said. “Can you drink the cup I drink or be baptized with the baptism I am baptized with?” [39] “We can,” they answered. Jesus said to them, “You will drink the cup I drink and be baptized with the baptism I am baptized with, [40] but to sit at my right or left is not for me to grant. These places belong to those for whom they have been prepared.” [41] When the ten heard about this, they became indignant with James and John.
