'Servant' in the Bible

A servant is Israel? Is he a child of the house? Wherefore hath he been for a prey?

Lo, I am sending, and have taken all the families of the north -- an affirmation of Jehovah -- even unto Nebuchadrezzar king of Babylon, My servant, and have brought them in against this land, and against its inhabitants, and against all these nations round about, and have devoted them, and appointed them for an astonishment, and for a hissing, and for wastes age-during.

And now, I -- I have given all these lands into the hand of Nebuchadnezzar king of Babylon, My servant, and also the beast of the field I have given to him to serve him;

And thou, be not afraid, My servant Jacob, An affirmation of Jehovah, Nor be affrighted, O Israel, For, lo, I am saving thee from afar, And thy seed from the land of their captivity, And Jacob hath turned back and rested, And is quiet, and there is none troubling.

Also My covenant is broken with David My servant, So that he hath not a son reigning on his throne, And with the Levites the priests, My ministers.

As the host of the heavens is not numbered, Nor the sand of the sea measured, So I multiply the seed of David My servant, And the Levites My ministers.'

Also the seed of Jacob, and David My servant, I reject, Against taking from his seed rulers For the seed of Abraham, Isaac, and Jacob, For I turn back to their captivity, and have pitied them.'

and thou hast said unto them: Thus said Jehovah of Hosts, God of Israel: 'Lo, I am sending, and I have taken Nebuchadrezzar king of Babylon, My servant, and I have set his throne above these stones that I have hid, and he hath stretched out his pavilion over them,

And thou, thou dost not fear, my servant Jacob, Nor art thou dismayed, O Israel, For lo, I am saving thee from afar, And thy seed from the land of their captivity, And Jacob hath turned back, And hath been at rest, and been at ease, And there is none disturbing.

Thou, thou dost not fear, My servant Jacob, An affirmation of Jehovah -- for with thee I am, For I make an end of all the nations Whither I have driven thee, And of thee I do not make an end, And I have reproved thee in judgment, And do not entirely acquit thee!'
