'King's' in the Bible

Saul commanded his servants, "Talk with David secretly, and say, 'Behold, the king has delight in you, and all his servants love you: now therefore be the king's son-in-law.'"

Saul's servants spoke those words in the ears of David. David said, "Does it seems to you a light thing to be the king's son-in-law, since I am a poor man, and lightly esteemed?"

Saul said, "You shall tell David, 'The king desires no dowry except one hundred foreskins of the Philistines, to be avenged of the king's enemies.'" Now Saul thought to make David fall by the hand of the Philistines.

When his servants told David these words, it pleased David well to be the king's son-in-law. The days were not expired;

and David arose and went, he and his men, and killed of the Philistines two hundred men; and David brought their foreskins, and they gave them in full number to the king, that he might be the king's son-in-law. Saul gave him Michal his daughter as wife.

He said, 'Please let me go, for our family has a sacrifice in the city. My brother has commanded me to be there. Now, if I have found favor in your eyes, please let me go away and see my brothers.' Therefore he has not come to the king's table."

David said to Ahimelech, "Isn't there here under your hand spear or sword? For I have neither brought my sword nor my weapons with me, because the king's business required haste."

Then Ahimelech answered the king, and said, "Who among all your servants is so faithful as David, who is the king's son-in-law, and is taken into your council, and is honorable in your house?

Now therefore, O king, come down, according to all the desire of your soul to come down; and our part shall be to deliver him up into the king's hand."

This thing isn't good that you have done. As Yahweh lives, you are worthy to die, because you have not kept watch over your lord, Yahweh's anointed. Now see where the king's spear is, and the jar of water that was at his head."
