Mark 10:36-40

And He said to them, “What do you want Me to do for you?”

They said to Him, “Grant that we may sit, one on Your right and one on Your left, in Your glory.”

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?”

They said to Him, “We are able.” And Jesus said to them, “The cup that I drink you shall drink; and you shall be baptized with the baptism with which I am baptized.

But to sit on My right or on My left is not Mine to give; but it is for those for whom it has been prepared.”
