Mark 10:38-40

38Jesus said to them, ‘You do not understand what you are asking for. I will have much pain and trouble. Are you ready to have the same pain? Are you ready to die in the way that I will die?’

39James and John replied, ‘Yes, we can do all that.’ Jesus said to them, ‘Yes, that is true. You will have pain like mine. And people will want to kill you like me.

40But I cannot promise that you will sit at my right side or at my left side. God has chosen the people who will sit there. He has prepared the places for those people.’
