Mark 10:42-45 NIV

[42] Jesus called them together and said, “You know that those who are regarded as rulers of the Gentiles lord it over them, and their high officials exercise authority over them. [43] Not so with you. Instead, whoever wants to become great among you must be your servant, [44] and whoever wants to be first must be slave of all. [45] For even the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.”
