20 And Michal daughter of Saul loveth David, and they declare to Saul, and the thing is right in his eyes, 21 and Saul saith, 'I give her to him, and she is to him for a snare, and the hand of the Philistines is on him;' and Saul saith unto David, 'By the second—thou dost become my son-in-law to-day.' 22 And Saul commandeth his servants, 'Speak unto David gently, saying, Lo, the king hath delighted in thee, and all his servants have loved thee, and now, be son-in-law to the king.' 23 And the servants of Saul speak in the ears of David these words, and David saith, 'Is it a light thing in your eyes to be son-in-law to the king—and I a poor man, and lightly esteemed?' 24 And the servants of Saul declare to him, saying, 'According to these words hath David spoken.' 25 And Saul saith, 'Thus do ye say to David, There is no delight to the king in dowry, but in a hundred foreskins of the Philistines—to be avenged on the enemies of the king;' and Saul thought to cause David to fall by the hand of the Philistines. 26 And his servants declare to David these words, and the thing is right in the eyes of David, to be son-in-law to the king; and the days have not been full, 27 and David riseth and goeth, he and his men, and smiteth among the Philistines two hundred men, and David bringeth in their foreskins, and they set them before the king, to be son-in-law to the king; and Saul giveth to him Michal his daughter 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!
