1 Samuel 18:20-27 New Revised Standard Version (NRSV)
20 Now Saul’s daughter Michal loved David. Saul was told, and the thing pleased him. 21 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,[a] “You shall now be my son-in-law.” 22 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.’” 23 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?” 24 The servants of Saul told him, “This is what David said.” 25 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. 26 When his servants told David these words, David was well pleased to be the king’s son-in-law. Before the time had expired, 27 David rose and went, along with his men, and killed one hundred[b] 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.
