'Servant' in the Bible

Is Israel a servant? is he a home-born'slave ? why is he become a prey?

behold, I will send and take all the families of the north, saith Jehovah, and I will send unto Nebuchadrezzar the king of Babylon, my servant, and will bring them against this land, and against the inhabitants thereof, and against all these nations round about; and I will utterly destroy them, and make them an astonishment, and a hissing, and perpetual desolations.

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

Therefore fear thou not, O Jacob my servant, saith Jehovah; neither be dismayed, O Israel: for, lo, I will save thee from afar, and thy seed from the land of their captivity; and Jacob shall return, and shall be quiet and at ease, and none shall make him afraid.

then may also my covenant be broken with David my servant, that he shall not have a son to reign upon his throne; and with the Levites the priests, my ministers.

As the host of heaven cannot be numbered, neither the sand of the sea measured; so will I multiply the seed of David my servant, and the Levites that minister unto me.

then will I also cast away the seed of Jacob, and of David my servant, so that I will not take of his seed to be rulers over the seed of Abraham, Isaac, and Jacob: for I will cause their captivity to return, and will have mercy on them.

but ye turned and profaned my name, and caused every man his servant, and every man his handmaid, whom ye had let go free at their pleasure, to return; and ye brought them into subjection, to be unto you for servants and for handmaids.

and say unto them, Thus saith Jehovah of hosts, the God of Israel: Behold, I will send and take Nebuchadrezzar the king of Babylon, my servant, and will set his throne upon these stones that I have hid; and he shall spread his royal pavilion over them.

But fear not thou, O Jacob my servant, neither be dismayed, O Israel: for, lo, I will save thee from afar, and thy seed from the land of their captivity; and Jacob shall return, and shall be quiet and at ease, and none shall make him afraid.

Fear not thou, O Jacob my servant, saith Jehovah; for I am with thee: for I will make a full end of all the nations whither I have driven thee; but I will not make a full end of thee, but I will correct thee in measure, and will in no wise leave thee unpunished.
