'Servant' in the Bible

But he made himself as nothing, taking the form of a servant, being made like men;

But it seemed to me necessary to send to you Epaphroditus, my brother, who has taken part with me in the work and in the fight, and your servant, sent by you for help in my need;

Not as if I had even now got the reward or been made complete: but I go on in the hope that I may come to the knowledge of that for which I was made the servant of Christ Jesus.
