Matthew 20:25-28

But Jesus called them unto him, and said, Ye know that the rulers of the Gentiles lord it over them, and their great ones exercise authority over them. Not so shall it be among you: but whosoever would become great among you shall be your minister; and whosoever would be first among you shall be your servant: even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.
