'Minister' in the Bible

Not so shall it be among you: but whosoever would become great among you shall be your minister;

even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.

Then shall they also answer, saying, Lord, when saw we thee hungry, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?
