That’s a very useful resource, Gottle of Geer. Thank you! I’ve posted some interpretations from that site here (I alternated with bold and normal to clearly mark where one commentary ends and the next begins):
CHUCK SMITH: The “handkerchiefs” were sweatbands that tied around the forehead. The people activated their faith at the point of contact when Paul’s articles were placed on them. The articles themselves had no power to heal but triggered the release of faith.
DAVID GUZIK: Luke states that these were
unusual miracles, and gives an example, that Paul’s
handkerchiefs or aprons (literally, “sweat-bands”) could be laid on a person even in Paul’s absence and that person would be healed or delivered from demonic possession
i. Literally, the phrase
unusual miracles is
miracles not of the ordinary kind; even if we should “expect” miracles, these are the unexpected sort!
b. How did these things work? In the same way that the shadow of Peter or the hem of Jesus’ garment might heal; in that they would become a point of contact by which a person would release faith in Jesus as healer
i. We are not told that Paul did these unusual miracles, but that God did them through the hands of Paul
c. We can imagine this happening at first almost by accident (a person in need of healing taking a handkerchief from Paul in a superstitious manner and being healed), but then became a pattern that others imitated
i. As we will see, the superstitious practice of magic and sorcery was prevalent in Ephesus; it should not surprise us that some took a quite superstitious view of the miracles done through Paul
d. Observations
i. Note that these were
unusual miracles; we should not expect that God would continue to use this method to bring healing
ii. God delights in doing things in new and different ways; so we
receive whatever is proven to be from the hand of God, but we
pursue only that which we have a Biblical pattern for
iii. God will stoop down to meet us even in our crude superstitions; this never means that God is pleased with them, but that in His mercy He may overlook them to meet a need.
MATTHEW HENRY: He not only cured the sick that were brought to him, or to whom he was brought, but *from his body were brought to the sick handkerchiefs or aprons; they got Paul’s handkerchiefs, or his aprons, that is, say some, the aprons he wore when he worked at his trade, and the application of them to the sick cured them immediately. Or, they brought the sick people’s handkerchiefs, or their girdles, or caps, or head-dresses, and laid them for awhile to Paul’s body, and then took them to the sick. The former is more probable. Now was fulfilled that word of Christ to his disciples, Greater works than these shall you do. We read of one that was cured by the touch of Christ’s garment when it was upon him, and he perceived that *virtue went out of him; but here were people cured by Paul’s garments when they were taken from him. Christ gave his apostles power against unclean spirits and against all manner of sickness (Mt. 10:1), and accordingly we find here that those to whom Paul sent relief had it in both those cases: *for *
the diseases departed from them and the
evil spirits went out of them, which were both significant of the great design and blessed effect of the gospel, and the healing of spiritual disease, and freeing the souls of men from the power and dominion of Satan. **
JAMIESON, FAUSETT & BROWN: So that from his body were brought unto the sick handkerchiefs or aprons, &c.–Compare
Act 5:15, 16 , very different from the magical acts practiced at Ephesus. “
God wrought these miracles” merely “
by the hands of Paul”; and the very exorcists (
Act 19:13 ), observing that the name of Jesus was the secret of all his miracles, hoped, by aping him in this, to be equally successful; while the result of all in the “magnifying of the Lord Jesus” (
Act 19:17 ) showed that in working them the apostle took care to hold up Him whom he
preached as the source of all the miracles which he
wrought.
