20 And Michal Saul's daughter loved David; and they told Saul, and the thing was right in his sight. 21 And Saul said, I will give him her, that she may be a snare to him, and that the hand of the Philistines may be upon him. And Saul said to David, Thou shalt this day be my son-in-law a second time. 22 And Saul commanded his servants, Speak with David secretly, saying, Behold, the king has delight in thee, and all his servants love thee: now therefore be the king's son-in-law. 23 And Saul's servants spoke those words in the ears of David. And David said, Is it a light thing in your eyes to be the king's son-in-law, seeing that I am a poor man, and lightly esteemed? 24 And the servants of Saul told him, saying, On this manner did David speak. 25 And Saul said, Thus shall ye say to David: The king does not desire any dowry, but a hundred foreskins of the Philistines, to be avenged of the king's enemies. But Saul thought to make David fall by the hand of the Philistines. 26 And his servants told David these words; and the thing was right in David's sight to be the king's son-in-law. And the days were not expired, 27 when David arose and went, he and his men, and smote of the Philistines two hundred men; and David brought their foreskins, and they delivered them in full to the king, that he might be the king's son-in-law. And Saul gave him Michal his daughter as 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!
