JMNT(i)
28 Now, upon seeing Jesus and uttering up a cry (or: crying aloud; screaming), he fell toward Him. And then in a loud voice he said, "What [is there] for me and for You (or: What [is the connection] to me, and in You; may = What do want with me), Jesus, Son of the Most High God? I beg (or: urgently request) You... You should not test my qualities or cause me pain or distress!"
29 You see, He began passing on an announcement and continued giving instruction to the unclean breath-effect (spirit; attitude; state of mind) to at once come out of the man. For many times it had seized and violently gripped him together (= took control of him), and he was from time to time being bound with and confined by chains and shackles (ankle fetters), being repeatedly guarded (or: kept in protective custody). And yet, repeatedly breaking the bonds in two, he kept on being driven (or: urged forward; impelled) away, from [other MSS: by; under] the demon (Hellenistic concept and term: = animistic influence; = an influence that was not part of him), into the uninhabited places (wilderness areas; desert regions; lonely places).
30 So Jesus asked him, "What is [the] name for you?" Now the man said, "Legion (or: An Army)," because many demons (= influences) at some point entered into him.
31 Then they began calling Him alongside for aid and assistance, entreating Him to the end that He would (might) not add directives and apply arrangements for (or: give orders to) them to go off into the Deep (the Abyss).
32 Now there was a considerable herd of pigs (hogs) being grazed (pastured) there, within the hill country (or: on the mountain), and so they entreated Him for assistance, to the end that He would proceed to allow (or: progressively permit) them to enter into those [pigs]. Then He gave permission to them.
