'King's' in the Bible

David said to Saul, “Who am I, and what is my life or my father’s family in Israel, that I should be the king’s son-in-law?”

So Saul’s servants spoke these words to David. But David said, “Is it a trivial thing in your sight to become a king’s son-in-law, seeing that I am a poor man and insignificant?”

Then Saul said, “This is what you shall say to David: ‘The king wants no dowry except a hundred foreskins of the Philistines, to take vengeance on the king’s enemies.’” Now Saul’s intention was to cause David’s death at the hand of the Philistines.

When his servants told David these words, it pleased him to become the king’s son-in-law. Before the time [for the marriage] arrived,

David arose and went, he and his men, and killed two hundred Philistine men, and David brought their foreskins [as proof of death] and presented every one of them to the king, so that he might become the king’s son-in-law. So Saul gave him Michal, his [younger] daughter, as a wife.

He said, ‘Please let me go because our family is holding a sacrifice in the city, and my brother has commanded me to attend. Now, if I have found favor in your eyes, please let me slip away so that I may see my brothers.’ That is why he has not come to the king’s table.”

David said to Ahimelech, “Do you not have a sword or spear here on hand? For I brought neither my sword nor my [other] weapons with me, because the king’s business was urgent.”

Then Ahimelech answered the king, “And who among all your servants is as faithful and trustworthy as David, who is the king’s son-in-law, and who is captain over your guard [and your confidant], and is honored in your house?

Now then, O king, come down [to Ziph] in accordance with all your heart’s desire to do so [and capture him]; and our part shall be to hand him over to the king.”

This thing that you have done is not good. As the Lord lives, you surely deserve to die, because you have not guarded your lord, the Lord’s anointed. And now, see where the king’s spear is, and the jug of water that was by his head.”

David answered, “Look, here is the king’s spear! Now let one of the young men come over and get it.
