Jesus unable to fulfill request

Mark 10

The Request of James and John

35 And James and John, the sons of Zeb′edee, 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 do 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 to be baptized with the baptism with which I am baptized?” 39 And they said to him, “We are able.” And 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.”

Matthew 20

A Mother’s Request

20 Then the mother of Zebedee’s sons came to Jesus with her sons and, kneeling down, asked a favor of him.

21 “What is it you want?” he asked.

She said, “Grant that one of these two sons of mine may sit at your right and the other at your left in your kingdom.”

22 “You don’t know what you are asking,” Jesus said to them. “Can you drink the cup I am going to drink?”

“We can,” they answered.

23 Jesus said to them, “You will indeed drink from my cup, 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 by my Father.”
