1 Samuel 19:15

“And Saul sent the messengers [again] to see David, etc.] Not to visit him, or to see how he was, or inquire of his health, in a kind manner, but to see his person, whether he was sick or not, and whether he was there or not; for Saul might suspect some deceit was used, because the messengers took the report of Michal, and saw not David, nor attempted to see him; but now they have strict orders to see him, and not take Michal’s word as before, (<091914>1 Samuel 19:14); wherefore the supplement again may be left out: saying, bring him up to me in the bed; if so bad that he was not able to rise, or not fit to be taken out of his bed, his orders were, that he should be brought to him in it;…”

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

“Bring him: The eastern beds consist merely of two thick cotton quilts, one of which, folded double, serves as a mattress, the other as a covering. Such seems to have been the bed of David, which could easily have been carried, with himself in it, to the presence of Saul. Sa1 19:6; Job 31:31; Psa 37:12; Pro 27:3, Pro 27:4; Rom 3:15 1 Kings (1 Samuel) 19:16”

“But when Saul sent the messengers again to see David, and that with the command, "Bring him up to me in the bed," and when they only found the teraphim in the bed, and Saul charged Michal with this act of deceit, she replied, "He (David) said to me, Let me go; why should I kill thee?" - "Behold, teraphim were (laid) in the bed." The verb can be naturally supplied from Sa1 19:13. In the words "Why should I kill thee?" Michael intimates that she did not mean to let David escape, but was obliged to yield to his threat that he would kill her if she continued to refuse. This prevarication she seems to have considered perfectly justifiable. 1 Kings (1 Samuel) 19:18”
