'Master' in the Bible

Then Jonathan called to him, “Hurry up and don’t stop!” Jonathan’s young man picked up the arrow and returned to his master.

One of Nabal’s young men informed Abigail, Nabal’s wife: “Look, David sent messengers from the wilderness to greet our master, but he yelled at them.

Now consider carefully what you must do, because there is certain to be trouble for our master and his entire family. He is such a worthless fool nobody can talk to him!”

Then David said to him, “Who do you belong to? Where are you from?”“I’m an Egyptian, the slave of an Amalekite man,” he said. “My master abandoned me when I got sick three days ago.

David then asked him, “Will you lead me to these raiders?”He said, “Swear to me by God that you won’t kill me or turn me over to my master, and I will lead you to them.”
