Thou hast. Hebrew, "thou wilt make. "Protestants, "turn "(marginal note; Haydock) "change, or take away. "In the east, the bed was removed entirely, (John v. 8.) and this expression may denote, (Calmet) that the sick man should be cured, and no longer be confined to his bed, (St. Chrysostom) or that God would take him by the hand, to support him, and turn his bed, like a tender mother, to make it more comfortable. (Genebrard) (Calmet)
