Matthew 20:24-28

And when the ten heard it, they were moved with indignation against the two brethren. But Jesus called them unto him, and said, Ye know that the princes of the Gentiles exercise dominion over them, and they that are great exercise authority upon 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 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.
