20 And Michal, Saul's daughter, loved David: and they told Saul, and the thing pleased him. 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 against him. Wherefore Saul said to David, Thou shalt this day be my son-in-law a second time. 22 And Saul commanded his servants, [saying], Commune with David secretly, and say, Behold, the king hath delight in thee, and all his servants love thee: now therefore be the king's son-in-law. 23 And Saul's servants spake those words in the ears of David. And David said, Seemeth it to you a light thing 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 spake David. 25 And Saul said, Thus shall ye say to David, The king desireth not any dowry, but a hundred foreskins of the Philistines, to 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. And the days were not expired; 27 and David arose and went, he and his men, and slew of the Philistines two hundred men; and David brought their foreskins, and they gave them in full number to the king, that he might be the king's son-in-law. And Saul gave him Michal his daughter to wife. 28 And Saul saw and knew that Jehovah was with David; and Michal, Saul's daughter, loved him. 29 And Saul was yet the more afraid of David; and Saul was David's enemy continually. 30 Then the princes of the Philistines went forth: and it came to pass, as often as they went forth, that David behaved himself more wisely than all the servants of Saul; so that his name was much set by.

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!
