'Master' in the Bible

David summoned Ziba the servant of Saul and said to him, "All that [was] Saul's and all his household I have given to the son of your master.

You shall till the land for him, you and your sons and your servants; you shall bring [in the produce] and it shall be food for the son of your master that he may eat. But Mephibosheth the son of your master may always eat food at my table." (Now Ziba had fifteen sons and twenty slaves.)

Ziba said to the king, "According to all that my master the king commands his servant, so your servant will do." So Mephibosheth [was] eating at his table as one of the sons of the king.

But the commanders of the {Ammonites} said to Hanun their master, "{In your opinion}, [is] David honoring your father because he has sent condolences to you? [Is] it not in order to search the city, to spy it out, and to overthrow it [that] David sent his servants to you?"

But Uriah slept [at] the entrance of the king's house with all the servants of his master and did not go down to his house.

I gave you the household of your master and the women of your master into your lap. I also gave you the house of Israel and Judah; if [that had been too] little, I would have added to you {much more}.
