Mark 10:41-45

When the ten other disciples heard what James and John had asked, they were indignant. So Jesus called them together and said, “You know that the rulers in this world lord it over their people, and officials flaunt their authority over those under them. But among you it will be different. Whoever wants to be a leader among you must be your servant, and whoever wants to be first among you must be the slave of everyone else. For even the Son of Man came not to be served but to serve others and to give his life as a ransom for many.”
