'Servant' in the Bible

so he asked the LORD, "Why did you bring all this trouble to your servant? Why haven't I found favor in your eyes? After all, you're putting the burden of this entire people on me!

But that's not how it is with my servant Moses, since he has been entrusted with my entire household!

I speak to him audibly and in visions, not in mysteries. If he can gaze at the image of the LORD, why aren't you afraid to speak against my servant Moses?"

Now as to my servant Caleb, because a different spirit is within him and he has remained true to me, I'm going to bring him into the land that he explored, and his descendants are to inherit it.
