He touched her hand - Can any thing on this side the unlimited power of God effect such a cure with only a touch? If the Scriptures had not spoken of the divinity of Christ, these proofs of his power must have demonstrated it to the common sense of every man whose creed had not previously blinded him.
Ministered unto them - Αυτοις, them, is the reading of most of the printed editions, but αυτω, to him, has the utmost evidence in its support from MSS., versions, and fathers. Serving Christ in his ordinances and in his members is the best proof we can give to others of our being soundly restored to spiritual health.

And he touched her hand,.... Sometimes he healed by a word, as the centurion's servant; and sometimes by a touch, as here; and sometimes by both, as the leper. Luke says, that he "stood over her", reached over her to take her by the hand, and lift her up, "and rebuked the fever". Just as he did the winds and sea, having all diseases, as well as the elements, at his beck and control;
and the fever left her immediately, as the other evangelists say.
And she arose and ministered unto them: the former of these actions is a proof of her being restored to health and strength, in so much that she could rise and walk about of herself; whereas generally, persons after fevers continue very weak a considerable time; which shows what a miracle was wrought upon her by Christ: and the latter of them expresses her gratitude, for the mercy she had received; she rises and serves him and his friends, preparing proper and suitable provisions for them.

Touched her hand. He could heal by a word, or by his touch. At his touch the fever left her.
Ministered. Was well, and able to prepare a meal for the Lord.
