Sorry about that realone - it's 1 Samuel 18:25-28. I found it in the New World Translation too:
25 At that Saul said: “This is what YOU men will say to David, ‘The king has delight, not in marriage money, but in a hundred foreskins of the Phi·lis´tines, to avenge himself on the enemies of the king.’” But as for Saul, he had schemed to have David fall by the hand of the Phi·lis´tines. 26 So his servants reported these words to David, and the matter was to David’s liking, to form a marriage alliance with the king, and the days had not yet expired. 27 So David rose and he and his men went and struck down among the Phi·lis´tines two hundred men, and David came bringing their foreskins and giving them in full number to the king, to form a marriage alliance with the king. In turn Saul gave him Mi´chal his daughter as a wife. 28 And Saul got to see and know that Jehovah was with David. As for Mi´chal, Saul’s daughter, she loved him.
And the New International Version
24 When Saul's servants told him what David had said, 25 Saul replied, "Say to David, 'The king wants no other price for the bride than a hundred Philistine foreskins, to take revenge on his enemies.' " Saul's plan was to have David fall by the hands of the Philistines.
26 When the attendants told David these things, he was pleased to become the king's son-in-law. So before the allotted time elapsed, 27 David and his men went out and killed two hundred Philistines. He brought their foreskins and presented the full number to the king so that he might become the king's son-in-law. Then Saul gave him his daughter Michal in marriage.
28 When Saul realized that the LORD was with David and that his daughter Michal loved David,
And the New Living Translation
24 When Saul’s men reported this back to the king, 25 he told them, “Tell David that all I want for the bride price is 100 Philistine foreskins! Vengeance on my enemies is all I really want.” But what Saul had in mind was that David would be killed in the fight.
26 David was delighted to accept the offer. Before the time limit expired, 27 he and his men went out and killed 200 Philistines. Then David fulfilled the king’s requirement by presenting all their foreskins to him. So Saul gave his daughter Michal to David to be his wife.
28 When Saul realized that the L ord was with David and how much his daughter Michal loved him, 29 Saul became even more afraid of him, and he remained David’s enemy for the rest of his life.
Praise the Lord, for he givith foreskins!
