'Servant' in the Bible

Thus said the Lord Jehovah: In My gathering the house of Israel, Out of the peoples among whom they were scattered, I have been sanctified in them, Before the eyes of the nations, And they have dwelt on their ground, That I gave to My servant, to Jacob,

And have raised up over them one shepherd, And he hath fed them -- my servant David, He doth feed them, and he is their shepherd,

And I, Jehovah, I am their God, And My servant David prince in their midst, I, Jehovah, have spoken.

And My servant David is king over them, And one shepherd have they all, And in My judgments they go, And My statutes they keep, and have done them.

And they have dwelt on the land that I gave to My servant, to Jacob, In which your fathers have dwelt, And they have dwelt on it, they and their sons, And their son's sons -- unto the age, And David My servant is their prince -- to the age.
