(20) And Michal Saul's daughter loved David.--But the love of the younger of the two royal princesses for her father's brilliant officer gave the unhappy king a fresh excuse to expose David's life to peril, while at the same time he appeared to be endeavouring to carry out an old formal promise.

Verses 20, 21. - Michal... loved David. Probably there was some short lapse of time between Merab's marriage and the growth of this affection, the news of which pleased Saul. He was not an ungenerous man, and possibly may have felt ashamed at having acted so meanly by David after having exposed him to danger. And yet evil thoughts again are uppermost, and his purposes are selfish; for either way Saul will be the gainer. David will probably be slain, he thinks, in trying to get the dowry asked of him; and if not, at all events he will himself be cleared of the stain of public dishonesty now resting upon him. Therefore Saul said to David. Not in person, which accounts for David giving no answer, but through his servants, as is recounted more fully afterwards.

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, Heb 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!And Michal, Saul's daughter, loved David,.... His youngest daughter fell in love with him, because of the comeliness of his person, his gallant behaviour, his wise conduct, and the general esteem and reputation he was had in, as may be supposed:

and they told Saul, and the thing pleased him; not that his daughter loved David, or that he should be his son-in-law, but that he should have an opportunity, as he hoped, of destroying David, which he had lost by giving his elder daughter to another; as also of retrieving his credit with the people, which was greatly sunk by using David in the manner he did, who had become the darling of the people.
