'Servant' in the Bible

And Moses said to the Lord, "Why have you afflicted your servant? Why have I not found favor in your sight, that you lay the burden of this entire people on me?

Joshua son of Nun, the servant of Moses, one of his choice young men, said, "My lord Moses, stop them!"

My servant Moses is not like this; he is faithful in all my house.

With him I will speak face to face, openly, and not in riddles; and he will see the form of the Lord. Why then were you not afraid to speak against my servant Moses?"

Only my servant Caleb, because he had a different spirit and has followed me fully -- I will bring him into the land where he had gone, and his descendants will possess it.
