Here is, I. Saul's further design of mischief to David. When David had escaped the javelin, supposing he went straight to his own house, as indeed he did, Saul sent some of his guards after him to lay wait at the door of his house, and to assassinate him in the morning as soon as he stirred out, Sa1 19:11. Josephus says the design was to seize him and to hurry him before a court of justice that was ordered to condemn him and put him to death as a traitor; but we are here told it was a shorter way they were to take with him: they were ordered to slay him. Well might David complain that his enemies were bloody men, as he did in the psalm which he penned at this time, and upon this occasion (Ps. 59), when Saul sent, and they watched the house to kill him. See Sa1 19:2, Sa1 19:3, and Sa1 19:7. He complains that swords were in their lips.
II. David's wonderful deliverance out of this danger. Michal was the instrument of it, whom Saul gave him to be a snare to him, but she proved to be his protector and helper. Often is the devil out-shot with his own bow. How Michal came to know the danger her husband was in does not appear; perhaps she had notice sent her from court, or rather was herself aware of the soldiers about the house, when they were going to bed, though they kept so still and silent that they said, Who dost hear? which David takes notice of, Psa 59:7. She, knowing her father's great indignation at David, soon suspected the design, and bestirred herself for her husband's safety. 1. She got David out of the danger. She told him how imminent the peril was (Sa1 19:11): Tomorrow thou wilt be slain. As Josephus paraphrases it, she told him that if the sun saw him there next morning it would never see him more; and then put him in a way of escape. David himself was better versed in the art of fighting than of flying, and had it been lawful it would have been easy for him to have cleared his house, by dint of sword, from those that haunted it; but Michal let him down through a window (Sa1 19:12), all the doors being guarded; and so he fled and escaped. And now it was that, either in his own closet before he went or in the hiding-place to which he fled, he penned that fifty-ninth Psalm, which shows that, in his fright and hurry, his mind was composed, and, in this great danger, his faith was strong and fixed on God; and, whereas the plot was to slay him in the morning, he speaks there with the greatest assurance (Sa1 19:16), I will sing aloud of thy mercy in the morning. 2. She practised a deception upon Saul and those whom he employed to be the instruments of his cruelty. When the doors of the house were opened in the morning, and David did not appear, the messengers would search the house for him, and did so. But Michal told them he was sick in bed (Sa1 19:14), and, if they would not believe her, they might see, for (Sa1 19:13) she had put a wooden image in the bed, and wrapped it up close and warm as if it had been David asleep, not in a condition to be spoken to; the goats' hair about the image was to resemble David's hair, the better to impose upon them. Michal can by no means be justified in telling a lie, and covering it thus with a cheat. God's truth needed not her lie. But she intended hereby to keep Saul in suspense for a while, that David might have some time to secure himself, not doubting but those messengers would pursue him if they found he had gone. The messengers had so much humanity as not to offer him any disturbance when they heard he was sick; for to those that are in this misery pity should be shown; but Saul, when he heard it, gave positive orders that he should be brought to him sick or well: Bring him to me in the bed, that I may slay him, Sa1 19:15. It was base and barbarous thus to triumph over a sick man; and to vow the death of one who for aught that he knew was dying by the hand of nature. So earnestly did he thirst after his blood, and so greedy was his revenge, that he could not be pleased to see him dead, unless he himself was the death of him; though awhile ago he had said, Let not my hand be upon him. Thus when men lay the reins on the neck of their passions they grow more and more outrageous. When the messengers were sent again, the cheat was discovered, Sa1 19:16. But by this time it was to be hoped that David was safe, and therefore Michal was not then much concerned at the discovery. Saul chid her for helping David to escape (Sa1 19:17): Why hast thou deceived me so? What a base spirit was Saul of, to expect that, because Michal was his daughter, she must therefore betray her own husband to him unjustly. Ought she not to forsake and forget her father and her father's house, to cleave to her husband? Those that themselves will be held by no bonds of reason or religion are ready to think that others should as easily break those bonds. In answer to Saul's chiding, Michal is not so careful of her husband's reputation as she had been of his person, when she makes this her excuse: He said, Let me go, why should I kill thee? As her insinuating that she would have hindered his flight was false (it was she that put him upon it and furthered it), so it was an unjust unworthy reflection upon him to suggest that he threatened to kill her if she would not let him go, and might confirm Saul in his rage against him. David was far from being so barbarous a man and so imperious a husband, so brutish in his resolves and so haughty in his menaces, as she here represented him. But David suffered both from friends and foes, and so did the son of David.

Let me go; why should I kill thee? - That is, If thou do not let me go, I will kill thee. This she said to excuse herself to her father: as a wife she could do not less than favor the escape of her husband, being perfectly satisfied that there was no guilt in him. It is supposed that it was on this occasion that David wrote the fifty-ninth Psalm, Deliver me from mine enemies, etc.

And Saul said unto Michal,.... After the messengers returned and reported what they had seen, when Saul either came to her at her house, or sent for her to his palace:

why hast thou deceived me so; for deceiving his messengers was deceiving him, by pretending David was sick and in bed, when she had placed an image there, and had let him down through a window, and he was gone:

and sent away mine enemy, that he is escaped? as if she was more obliged to gratify the wicked passion of a father, than to provide for the safety of her husband:

and Michal answered Saul, he said unto me, let me go, why should I kill thee? though she was concerned for the preservation of her husband, yet not for his honour and credit, nor for her own veracity; she attempted not to vindicate her husband from the charge of being an enemy to Saul, as she might; but suggested that he was so desperate a man, that if she had offered to have detained him, he would have murdered her, and threatened, if she did, he would do when both were false; that he should say to her let me go, when it was she that advised him to go, and that if she refused he would kill her; which lies were framed by her to excuse herself, at the expense of her husband's reputation.

Bring him to me in the bed--a portable couch or mattress.
