JMNT(i)
13 So certain folks who were a part of the constantly wandering (or: periodically roving; habitually vagabond) Jews – being practicing exorcists (folks who exacted or administered oaths; people who pronounced incantations) – also took in hand (= ventured; undertook) to be repeatedly naming the Name of the Lord Jesus upon folks continuing in having miserable spirits (breath-effects or attitudes which bring pain, bad conditions, unsoundness, wickedness and evil), habitually saying, "I am now administering as an oath upon you folks (or: adjuring and solemnly charging you people by) the Jesus whom Paul is now repeatedly proclaiming (publicly heralding)!"
14 Now there were seven sons of a certain Sceva (or: Sceuas), a Jewish chief priest, repeatedly performing this [D and p38 read: desired to do this].
15 [D and p38 add: They continued having a habit (or: custom) such as these things, to proceed in performing an exorcism. And so, upon entering to face the person affected by a demon (a Hellenistic religious word and concept), they began to repeatedly have the Name called upon, repeated saying, "In union with {the} Jesus, whom Paul continues preaching, we are now commanding and passing along this announcement to you, to come (or: go) out at once!"] But making a discerning reply, the miserable spirit (or: the malicious and mischievous breath-effect) said to them, "Indeed, from experience I recognize and have insight about Jesus, and I am learning of, and becoming increasingly acquainted with, Paul, but now who (or: what [sort of] men) are you folks?"
16 And then suddenly leaping (springing like a panther) upon them, the man within whom was the miserable breath-effect (the bad spirit or attitude) – in coming down as master and owner of both of them (= two at a time; or, thus: = all of them, one after another) – exerted [his] strength down on and against them (= prevailed over them), with the result that, naked and having been wounded and traumatized, [they managed] to make an escape (to flee out) from that house.
