The thing pleased him - It partly relieved him from the charge of breaking his faith.

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.

Michal is married to David. - The pretext under which Saul broke his promise is not given, but it appears to have been, at any rate in part, that Merab had no love to David. This may be inferred from 1 Samuel 18:17, 1 Samuel 18:18, compared with 1 Samuel 18:20. Michal, the younger daughter of Saul, loved David. When Saul was told this, the thing was quite right in his eyes. He said, "I will give her to him, that she may become a snare to him, and the hand of the Philistines may come upon him" (sc., if he tries to get the price which I shall require a dowry; cf. 1 Samuel 18:25). He therefore said to David, "In a second way (בּשׁתּים, as in Job 33:14) shalt thou become my son-in-law." Saul said this casually to David; but he made no reply, because he had found out the fickleness of Saul, and therefore put no further trust in his words.

And Michal Saul's daughter loved David: and they told Saul, and the thing pleased him.

pleased him: Heb. was right in his eyes

20. Michal Saul's daughter loved David-This must have happened some time after.

they told Saul, and the thing pleased him-Not from any favor to David, but he saw that it would be turned to the advancement of his malicious purposes, and the more so when, by the artful intrigues and flattery of his spies, the loyal sentiments of David were discovered.

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!
