'Servant' in the Bible

behold, I will send and take all the families of the north, saith Jehovah, and I will send to 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 wastes.

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

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

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

As the host of the heavens cannot be numbered, nor 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 as not to take of his seed to be rulers over the seed of Abraham, Isaac, and Jacob: for I will turn their captivity, and will have mercy on them.

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 which I have hidden, and he shall spread his royal pavilion over them.

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

Fear thou not, my servant Jacob, 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 with judgment, and I will not hold thee altogether guiltless.
