Mark 10:39 In-Context

37 They answered, "When you sit on your throne in your glorious Kingdom, we want you to let us sit with you, one at your right and one at your left."
38 Jesus said to them, "You don't know what you are asking for. Can you drink the cup of suffering that I must drink? Can you be baptized in the way I must be baptized?"
39 "We can," they answered. Jesus said to them, "You will indeed drink the cup I must drink and be baptized in the way I must be baptized.
40 But I do not have the right to choose who will sit at my right and my left. It is God who will give these places to those for whom he has prepared them."
41 When the other ten disciples heard about it, they became angry with James and John.
