Mark 10:39

36 And he said to them, What would you have me do for you?

37 And they said to him, Let us be seated, one at your right hand and one at your left, in your glory.

38 But Jesus said to them, You have no knowledge of what you are saying. Are you able to take of my cup? or to undergo the baptism which I am to undergo?

39 And they said to him, We are able. And Jesus said to them, You will take of the cup from which I take; and the baptism which I am about to undergo you will undergo:

40 But to be seated at my right hand or at my left is not for me to give: but it is for those for whom it has been made ready.

41 And hearing this, the ten became very angry with James and John.

42 And Jesus made them come to him, and said to them, You see that those who are made rulers over the Gentiles are lords over them, and their great ones have authority over them.
