'King's' in the Bible

Then David responded, “Who am I, and what is my family or my father’s clan in Israel that I should become the king’s son-in-law?”

And Saul commanded his servants, saying, Commune with David secretly, and say, Behold, the king hath delight in thee, and all his servants love thee: now therefore be the king's son in law.

And Saul's servants spake those words in the ears of David. And David said, Seemeth it to you a light thing to be a king's son in law, seeing that I am a poor man, and lightly esteemed?

And Saul said, Thus shall ye say to David, The king desireth not any dowry, but an hundred foreskins of the Philistines, to be avenged of the king's enemies. But Saul thought to make David fall by the hand of the Philistines.

And when his servants told David these words, it pleased David well to be the king's son in law: and the days were not expired.

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

And he said, Let me go, I pray thee; for our family hath a sacrifice in the city; and my brother, he hath commanded me to be there: and now, if I have found favour in thine eyes, let me get away, I pray thee, and see my brethren. Therefore he cometh not unto the king's table.

And David said unto Ahimelech, And is there not here under thine 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, And who is so faithful among all thy servants as David, which is the king's son in law, and goeth at thy bidding, and is honourable in thine house?

Then the king ordered the guards standing by him, “Turn and kill the priests of the Lord because they sided with David. For they knew he was fleeing, but they didn’t tell me.” But the king’s servants would not lift a hand to execute the priests of the Lord.

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

This thing is not good that thou hast done. As the LORD liveth, ye are worthy to die, because ye have not kept your master, the LORD'S anointed. And now see where the king's spear is, and the cruse of water that was at his bolster.

And David answered and said, Behold the king's spear! and let one of the young men come over and fetch it.

Then David said to Achish, If now I have grace in your eyes, let me have a place in one of the smaller towns of your land, to be my living-place; for it is not right for your servant to be living with you in the king's town.
