'Servant' in the Bible

‘Thus says the Lord God, “When I gather the house of Israel from the nations among whom they are scattered, and I manifest my Holiness in them in the sight of the nations, then they will live in their own land which I gave to My servant Jacob.

“Then I will appoint over them one shepherd and he will feed them, [a ruler like] My servant David; he will feed them and be their shepherd.

And I the Lord will be their God, and My servant David will be a prince among them; I the Lord have spoken.

“My servant David will be king over them, and they all will have one shepherd. They will also walk in My ordinances and keep My statutes and observe them.

They will live in the land where your fathers lived, [the land] that I gave to My servant Jacob, and they will live there, they and their children and their children’s children, forever; and My servant David will be their leader forever.
