'Master' in the Bible

And Jonathan called after the lad, “Hurry, be quick, do not stay!” And Jonathan’s lad picked up the arrow and came to his master.

But Nabal answered David’s servants and said, “Who is David? And who is the son of Jesse? There are many servants today who are each breaking away from his master.

But one of the young men told Abigail, Nabal’s wife, saying, “Behold, David sent messengers from the wilderness to greet our master, and he scorned them.

Now therefore, know and consider what you should do, for evil is plotted against our master and against all his household; and he is such a worthless man that no one can speak to him.”

David said to him, “To whom do you belong? And where are you from?” And he said, “I am a young man of Egypt, a servant of an Amalekite; and my master left me behind when I fell sick three days ago.

Then David said to him, “Will you bring me down to this band?” And he said, “Swear to me by God that you will not kill me or deliver me into the hands of my master, and I will bring you down to this band.”
