'Servant' in the Bible

And {when he came near} to the pit, he cried out to Daniel with distressed voice, [and] the king {spoke} and said to Daniel, "O Daniel, servant of the living God, your God whom you serve faithfully, was he able to rescue you from the lions?"

"And all Israel transgressed your law and turned aside [so as] not to listen to your voice, and [so] the curse and the oath which [was] written in the law of Moses, the servant of God, has been poured out upon us, because we have sinned against him.

"And now, listen to the prayer of your servant and to his pleas for mercy. Shine your face upon your desolate sanctuary {for your sake, O Lord}.

So {how am I, a servant of my lord} to speak with {you, my lord}, and I {just now} {have no strength in me}?"
