'Master's' in the Bible

Then the king called to Ziba, Saul's servant, and said unto him, I have given unto thy master's son all that pertained to Saul and to all his house.

Thou therefore, and thy sons, and thy servants, shall till the land for him, and thou shalt bring in the fruits, that thy master's son may have food to eat: but Mephibosheth thy master's son shall eat bread alway at my table. Now Ziba had fifteen sons and twenty servants.

But Uriah slept at the door of the palace with all his master’s servants; he did not go down to his house.

Uriah replied, "The ark, along with Israel and Judah, are encamped in tents, while my commanding officer Joab and my master's staff members are camping out in the open fields. Should I go home, eat, drink, and have sex with my wife? Not on your life! I won't do something like this, will I?"

Then David invited Uriah to eat and drink with him, and David got him drunk. He went out in the evening to lie down on his cot with his master’s servants, but he did not go home.

And I gave thee thy master's house, and thy master's wives into thy bosom, and gave thee the house of Israel and of Judah; and if that had been too little, I would moreover have given unto thee such and such things.

And the king said, And where is thy master's son? And Ziba said unto the king, Behold, he abideth at Jerusalem: for he said, To day shall the house of Israel restore me the kingdom of my father.
