Mark 10:42-45

So Jesus called them all together to him and said, “You know that those who are considered rulers of the heathen have power over them, and the leaders have complete authority. This, however, is not the way it is among you. If one of you wants to be great, you must be the servant of the rest; and if one of you wants to be first, you must be the slave of all. For even the Son of Man did not come to be served; he came to serve and to give his life to redeem many people.”
