'Servant' in the Bible

And Moses said to Jehovah, Why hast thou done evil to thy servant, and why have I not found favour in thine eyes, that thou layest the burden of all this people upon me?

Not so my servant Moses: he is faithful in all my house.

Mouth to mouth do I speak to him openly, and not in riddles; and the form of Jehovah doth he behold. Why then were ye not afraid to speak against my servant, against Moses?

But my servant Caleb, because he hath another spirit in him, and hath followed me fully, him will I bring into the land whereinto he came; and his seed shall possess it.
