Humans seem to have been participants in the events summarized by Paul as “ . . . Satan stopped us,” (details below) just as they were in the satanically-initiated raids that plundered Job’s property and killed his children (Job 1:13-16,17-19). Likewise, the fulfillment of “ . . the devil is about to throw some of you into prison, that you may be tested . . .” (Revelation 2:10) presumably involved humans as well as supernatural powers, and a similar mix of humans and spiritual powers was involved in Jesus’ death (Luke 22:3-4; John 13:2).

Then the brothers immediately sent out Paul to go as far as to the sea . . .
