'Servant's' in the Bible

And he said, Behold now, my lords, turn in, I pray you, into your servant's house, and tarry all night, and wash your feet, and ye shall rise up early, and go on your ways. And they said, Nay; but we will abide in the street all night.

Howbeit I will not take the whole kingdom out of his hand: but I will make him prince all the days of his life for David my servant's sake, whom I chose, because he kept my commandments and my statutes:

And yet this was a small thing in thine eyes, O God; for thou hast also spoken of thy servant's house for a great while to come, and hast regarded me according to the estate of a man of high degree, O LORD God.

O LORD, for thy servant's sake, and according to thine own heart, hast thou done all this greatness, in making known all these great things.

For Jacob my servant's sake, and Israel mine elect, I have even called thee by thy name: I have surnamed thee, though thou hast not known me.
