And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure.
All Commentaries on 2 Corinthians 12:7 Go To 2 Corinthians 12
John Chrysostom
AD 407
There are some who have said that Paul is referring to a pain in the head caused by the devil, but God forbid! The body of Paul could never have been given over to the devil, especially when we remember that the devil submitted to Paul when he was bidden to. In Hebrew, any adversary can be called Satan. What Paul means is that God would not allow the preaching of the gospel to go forward, so that his proud thoughts might be checked. Instead, Paul was attacked by adversaries like Alexander the coppersmith, the party of Hymenaeus and Philetus and all the opponents of the Word. These were the messengers of Satan.
