When Jesus and the twelve disciples were together the mother of James and John came to ask Jesus a question.
“Jesus asked, “What do you want?” She said, “Promise that one of my sons will sit at your right side and the other will sit at your left side in your kingdom.””
Matthew 20:21 NCV

“When the ten others heard about this, they lost their tempers, thoroughly disgusted with the two brothers. So Jesus got them together to settle things down. He said, “You’ve observed how godless rulers throw their weight around, how quickly a little power goes to their heads. It’s not going to be that way with you. Whoever wants to be great must become a servant. Whoever wants to be first among you must be your slave. That is what the Son of Man has done: He came to serve, not be served—and then to give away his life in exchange for the many who are held hostage.””
