Matthew 20:27

Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.

And he came to Capernaum: and being in the house he asked them, What was it that ye disputed among yourselves by the way? But they held their peace: for by the way they had disputed among themselves, who should be the greatest. And he sat down, and called the twelve, and saith unto them, If any man desire to be first, the same shall be last of all, and servant of all.

But ye shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve.

Yea, ye yourselves know, that these hands have ministered unto my necessities, and to them that were with me.

I am debtor both to the Greeks, and to the Barbarians; both to the wise, and to the unwise.

For though I be free from all men, yet have I made myself servant unto all, that I might gain the more. And unto the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law, that I might gain them that are under the law; To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law. To the weak became I as weak, that I might gain the weak: I am made all things to all men, that I might by all means save some. And this I do for the gospel's sake, that I might be partaker thereof with you.
