David went out and was successful wherever Saul sent him; as a result, Saul set him over the army. And all the people, even the servants of Saul, approved.
As they were coming home, when David returned from killing the Philistine, the women came out of all the towns of Israel, singing and dancing, to meet King Saul, with tambourines, with songs of joy, and with musical instruments.
Saul was very angry, for this saying displeased him. He said, "They have ascribed to David ten thousands, and to me they have ascribed thousands; what more can he have but the kingdom?"
The next day an evil spirit from God rushed upon Saul, and he raved within his house, while David was playing the lyre, as he did day by day. Saul had his spear in his hand;
Then Saul said to David, "Here is my elder daughter Merab; I will give her to you as a wife; only be valiant for me and fight the LORD's battles." For Saul thought, "I will not raise a hand against him; let the Philistines deal with him."
Saul thought, "Let me give her to him that she may be a snare for him and that the hand of the Philistines may be against him." Therefore Saul said to David a second time, "You shall now be my son-in-law."
Saul commanded his servants, "Speak to David in private and say, 'See, the king is delighted with you, and all his servants love you; now then, become the king's son-in-law.'"
So Saul's servants reported these words to David in private. And David said, "Does it seem to you a little thing to become the king's son-in-law, seeing that I am a poor man and of no repute?"
Then Saul said, "Thus shall you say to David, 'The king desires no marriage present except a hundred foreskins of the Philistines, that he may be avenged on the king's enemies.'" Now Saul planned to make David fall by the hand of the Philistines.
David rose and went, along with his men, and killed one hundred of the Philistines; and David brought their foreskins, which were given in full number to the king, that he might become the king's son-in-law. Saul gave him his daughter Michal as a wife.
Then the commanders of the Philistines came out to battle; and as often as they came out, David had more success than all the servants of Saul, so that his fame became very great.
