8) A Legion of Unclean spirits
Mar 5:1-9 And they came to the other side of the sea, into the country of the Gerasenes. And when he was come out of the boat, straightway there met him out of the tombs a man with an unclean spirit, who had his dwelling in the tombs: and no man could any more bind him, no, not with a chain; because that he had been often bound with fetters and chains, and the chains had been rent asunder by him, and the fetters broken in pieces: and no man had strength to tame him. And always, night and day, in the tombs and in the mountains, he was crying out, and cutting himself with stones. And when he saw Jesus from afar, he ran and worshipped him; and crying out with a loud voice, he saith, What have I to do with thee, Jesus, Thou Son of The MOST HIGH GOD? I adjure Thee by GOD, torment me not. For He said unto him, Come forth, thou unclean spirit, out of the man. And He asked him, What is thy name? And he saith unto Him, My name is Legion; for we art many.
G169 akáthartos; gen. akathártou, masc.-fem., neut. akátharton, adj. from the priv. a (G1), without, and kathaírō (G2508), to cleanse. Unclean.
Unclean as applied to the devils who are frequently called unclean spirits in the NT because, having lost their original purity, they are become unclean themselves and through their solicitations have polluted mankind with all uncleanness and every abomination which the Lord hates (Mar 5:2, Mar 5:8, Mar 5:13. See also Mat 10:1; Mat 12:43; Mar 1:23, Mar 1:26-27; Mar 3:11, Mar 3:30; Mar 6:7; Mar 7:25; Mar 9:25; Luk 4:33, Luk 4:36; Luk 6:18; Luk 8:29; Luk 9:42; Luk 11:24; Act 5:16; Act 8:7; Rev 16:13).
G3003 legeṓn; gen. legeṓnos, Lat. legio, A masculine noun. A legion, which is the largest division of troops in the Roman army, varying greatly in number at different periods as 3,000; 4,200; 5,000; 6,600. Used for an indefinitely great number of angels (Mat 26:53); of demons (Mar 5:9, Mar 5:15; Luk 8:30).
Additional scripture references related to the identification of this stronghold:
Mat 8:28 And when he was come to the other side into the country of the Gadarenes, there met him two possessed with devils, coming forth out of the tombs, exceeding fierce, so that no man could pass by that way.
Luk 8:29 For he commanded the unclean spirit to come out from the man. For oftentimes it had seized him: and he was kept under guard, and bound with chains and fetters; and breaking the bands asunder, he was driven of the devil into the deserts.
A large amount of demons acting jointly together as a stronghold. A person under such a strong influence of demonic power can demonstrate superhuman strength, violent and untamable behavior, criminal activities, and at times deliberate self-injury/harm tendencies, as was described in the text by him cutting himself with stones. This stronghold is easily able to take over a person’s will. It is a very strong demonic force to remove. It was able to resist Jesus to some degree.
