Matthew 20:25-28

But Jesus called them unto him and said, Ye know that the princes of the Gentiles exercise dominion over them, and those that are great wield power over them. But it shall not be so among you, but whosoever will be great among you, let him be your minister; and whosoever will be chief among you, let him be your slave, even as the Son of man came not to be ministered unto, but to minister and to give his life a ransom for many.
