Mark 10:35-38

James and John, the two sons of Zebedee, came to Him, saying, “Teacher, we want You to do for us whatever we ask of You.” [Matt 20:20, 21] And He replied to them, “What do you want Me to do for you?” They said to Him, “Grant that we may sit [with You], one on Your right and one on Your left, in Your glory [Your majesty and splendor in Your kingdom].” 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 [of suffering and death] with which I am baptized?”
