'Servant' in the Bible

Thus says the Lord Yahweh: "When I gather the house of Israel from the peoples to which they were scattered [about] in them, and I show myself holy in them before the eyes of the nations, then they will live on their soil, which I gave to my servant Jacob.

And I will set up over them one shepherd, and he will feed them; [that is], my servant David. He will feed them, and he will be for them as a shepherd.

And I, Yahweh, I will be for them {as God}, and my servant David [will be] a leader in the midst of them. I, Yahweh, I have spoken.

" '"And my servant David [will be] king over them, and one shepherd will be for all of them, and in my regulations they will go, and my statutes they will observe, and they will do them.

And they will dwell on the land that I gave to my servant, to Jacob, {in which your ancestors dwelled}, and they will dwell on it, they and their children and the children of their children {forever}, and my servant David [will be] a leader for them {forever}.
