'King's' in the Bible

David said to Saul, "Who am I? Who are my relatives or the clan of my father in Israel that I should become the king's son-in-law?"

Then Saul instructed his servants, "Tell David secretly, 'The king is pleased with you, and all his servants like you. So now become the king's son-in-law."

So Saul's servants spoke these words privately to David. David replied, "Is becoming the king's son-in-law something insignificant to you? I'm just a poor and lightly-esteemed man!"

So his servants told David these things and David agreed to become the king's son-in-law. Now the specified time had not yet expired

when David, along with his men, went out and struck down two hundred Philistine men. David brought their foreskins and presented all of them to the king so he could become the king's son-in-law. Saul then gave him his daughter Michal in marriage.

He said, 'Permit me to go, for we are having a family sacrifice in the city, and my brother urged me to be there. So now, if I have found favor with you, let me go to see my brothers.' For that reason he has not come to the king's table."

David said to Ahimelech, "Is there no sword or spear here at your disposal? I don't have my own sword or equipment in hand due to the urgency of the king's instructions."

Ahimelech replied to the king, "Who among all your servants is faithful like David? He is the king's son-in-law, the leader of your bodyguard, and honored in your house!

Then the king said to the messengers who were stationed beside him, "Turn and kill the priests of the Lord, for they too have sided with David! They knew he was fleeing, but they did not inform me." But the king's servants refused to harm the priests of the Lord.

Now at your own discretion, O king, come down. Delivering him into the king's hand will be our responsibility."

This failure on your part isn't good! As surely as the Lord lives, you people who have not protected your lord, the Lord's chosen one, are as good as dead! Now look where the king's spear and the jug of water that was by his head are!"

David replied, "Here is the king's spear! Let one of your servants cross over and get it.
