1 Samuel 18:22-30

22Then 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.”

23So 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!”

24When Saul’s servants reported what David had said,

25Saul replied, “Here is what you should say to David: ‘There is nothing that the king wants as a price for the bride except a hundred Philistine foreskins, so that he can be avenged of his enemies.’” (Now Saul was thinking that he could kill David by the hand of the Philistines.)

26So 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

27when 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.

28When Saul realized that the Lord was with David and that his daughter Michal loved David,

29Saul became even more afraid of him. Saul continued to be at odds with David from then on.

30Then the leaders of the Philistines would march out, and as often as they did so, David achieved more success than all of Saul’s servants. His name was held in high esteem.
