24 And the servants of Saul told him, "Thus and so did David speak." 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 of the king's enemies.'" Now Saul thought to make David fall by the hand of the Philistines. 26 And when his servants told David these words, it pleased David well to be the king's son-in-law. Before the time had expired, 27 David arose and went, along with his men, and killed two 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. And Saul gave him his daughter Michal for a wife.

Commentary on 1 Samuel 18:12-30
(Read 1 Samuel 18:12-30)
For a long time David was kept in continual apprehension of falling by the hand of Saul, yet he persevered in meek and respectful behaviour towards his persecutor. How uncommon is such prudence and discretion, especially under insults and provocations! Let us inquire if we imitate this part of the exemplary character before us. Are we behaving wisely in all our ways? Is there no sinful omission, no rashness of spirit, nothing wrong in our conduct? Opposition and perverseness in others, will not excuse wrong tempers in us, but should increase our care, and attention to the duties of our station. Consider Him that endured contradiction of sinners against himself, lest ye be weary and faint in your minds, Hebrews 12:3. If David magnified the honour of being son-in-law to king Saul, how should we magnify the honour of being sons to the King of kings!
