'Servant' in the Bible

As he approached the den, he called out to Daniel in a worried voice, "Daniel, servant of the living God, was your God whom you continually serve able to rescue you from the lions?"

"All Israel has broken your law and turned away by not obeying you. Therefore you have poured out on us the judgment solemnly threatened in the law of Moses the servant of God, for we have sinned against you.

"So now, our God, accept the prayer and requests of your servant, and show favor to your devastated sanctuary for your own sake.
