Laid upon the bed - The demon having tormented her, so that her bodily strength was exhausted, and she was now laid upon the couch to take a little rest. The Ethiopic has a remarkable reading here, which gives a very different, and, I think, a better sense. And she found her daughter Clothed, Sitting upon the couch, and the demon gone out.

And when she was come to her house,.... For with those words of Christ; she was abundantly satisfied, and went away with as great a faith, and as strong a persuasion of the dispossession, as that she came with, that Christ was able to effect it: and accordingly
she found the devil gone out; of her daughter; that she was entirely dispossessed of him, and no more vexed and tormented with him, but in perfect ease, and at rest:
and her daughter laid upon the bed; without any violent motions, convulsions, and tossings to and fro, as before; but composed and still, taking some rest, having been for some time greatly fatigued with the possession. The Ethiopic version reads, "she found her daughter clothed, and sat upon the bed": for persons in these possessions, would often put off their clothes, and tear them in pieces; and were seldom composed, and rarely sat long in a place or posture; but now it was otherwise with her.

And when she was come to her house, she found the devil gone out, and her daughter laid upon the bed--But Matthew (Matthew 15:28) is more specific; "And her daughter was made whole from that very hour." The wonderfulness of this case in all its features has been felt in every age of the Church, and the balm it has administered, and will yet administer, to millions will be known only in that day that shall reveal the secrets of all hearts.
