35 James and John, the sons of Zebedee, came forward to him and said to him, "Teacher, we want you to do for us whatever we ask of you." 36 And he said to them, "What is it you want me to do for you?" 37 And they said to him, "Grant us to sit, one at your right hand and one at your left, in your glory." 38 But Jesus said to them, "You do not know what you are asking. Are you able to drink the cup that I drink, or be baptized with the baptism that I am baptized with?" 39 They replied, "We are able." Then Jesus said to them, "The cup that I drink you will drink; and with the baptism with which I am baptized, you will be baptized; 40 but to sit at my right hand or at my left is not mine to grant, but it is for those for whom it has been prepared."

Commentary on Mark 10:32-45
(Read Mark 10:32-45)
Christ's going on with his undertaking for the salvation of mankind, was, is, and will be, the wonder of all his disciples. Worldly honour is a glittering thing, with which the eyes of Christ's own disciples have many times been dazzled. Our care must be, that we may have wisdom and grace to know how to suffer with him; and we may trust him to provide what the degrees of our glory shall be. Christ shows them that dominion was generally abused in the world. If Jesus would gratify all our desires, it would soon appear that we desire fame or authority, and are unwilling to taste of his cup, or to have his baptism; and should often be ruined by having our prayers answered. But he loves us, and will only give his people what is good for them.
