'Servant' in the Bible

"Is Israel a slave, or was he born a servant? Why then has he become plunder?

I'm now sending for all the tribes from the north, declares the LORD, and for my servant Nebuchadnezzar king of Babylon. I'll bring them against this land, against its inhabitants, and against all these surrounding nations. I'll utterly destroy them and make them an object of horror and scorn, and an everlasting desolation.

Now I've given all these lands to my servant, Nebuchadnezzar king of Babylon, and I've even given him the wild animals to serve him.

"My servant Jacob, don't be afraid,' declares the LORD, "and Israel, don't be dismayed. For I'll deliver you from a distant place and your descendants from the land of their captivity. Jacob will return. He will be undisturbed and secure, and no one will cause him to fear.

then my covenant with my servant David might also be broken so that he wouldn't have a son sitting on his throne, and so also with my servants the Levitical priests.

As the heavenly bodies cannot be counted, and the sands of the sea cannot be measured, so I'll multiply the descendants of my servant David and the descendants of Levi who serve me.'"

then I might reject the descendants of Jacob and my servant David by not taking some of his descendants as rulers over the descendants of Abraham, Isaac, and Jacob. Indeed, I'll restore their fortunes, and I'll have compassion on them.'"

Then say to them, "This is what the LORD of the Heavenly Armies, the God of Israel, says: "I'm going to send for my servant Nebuchadnezzar king of Babylon. I'll take him and set his throne over these stones that I've buried, and he will spread his canopy over them.

"As for you, my servant Jacob, don't be afraid, and Israel, don't be dismayed. For I'll deliver you from a distant place, and your descendants from the land of their captivity. Jacob will return. He will be undisturbed and secure, and no one will cause him to fear.

"As for you, my servant Jacob, don't be afraid, and Israel, don't be dismayed," declares the LORD, "for I am with you. Indeed, I'll make an end of all the nations where I scattered you; but I won't make an end of you! I'll discipline you justly, but I'll certainly not leave you unpunished."
