Scripture seems to express about 2,000 pigs bolted to the water.
The word legion simply mean many. When one comes they all come .You could say unity of the lying spirit the god of this world.
A good example in found in 1 Samuel 28 . as a source of necromancy seeking after familiar spirits of the departed
And when Saul enquired of the Lord, the Lord answered him not, neither by dreams, nor by Urim, nor by prophets. Then said Saul unto his servants, Seek me a woman that hath a familiar spirit, that I may go to her, and enquire of her. And his servants said to him, Behold, there is a woman that hath a familiar spirit at Endor. And Saul disguised himself, and put on other raiment, and he went, and two men with him, and they came to the woman by night: and he said, I pray thee, divine unto me by the familiar spirit, and bring me him up, whom I shall name unto thee. And the woman said unto him, Behold, thou knowest what Saul hath done, how he hath cut off those that have familiar spirits, and the wizards, out of the land: wherefore then layest thou a snare for my life, to cause me to die?And Saul sware to her by the Lord, saying, As the Lord liveth, there shall no punishment happen to thee for this thing. Then said the woman,
Whom shall I bring up unto thee? And he said, Bring me up Samuel. And when the woman saw Samuel, she cried with a loud voice: and the woman spake to Saul, saying, Why hast thou deceived me? for thou art Saul. And the king said unto her, Be not afraid: for what sawest thou? And the woman said unto Saul, I saw gods ascending out of the earth. And he said unto her, What form is he of? And she said, An old man cometh up; and he is covered with a mantle. And Saul perceived that it was Samuel, and he stooped with his face to the ground, and bowed himself.! Samuel 28:6-14
There the mediator of necromancy called a witch when seeking the departed asked who she should call up ? When Saul said Samuel she was afraid .Saul tried to comfort her and said what did you see? And she said; I saw gods (legion) ascending out of the earth as in many or again establishing the legion. Saul then asked what form, she gave him a description An old man cometh up; and he is covered with a mantle and then Saul believed it was Samuel.using the form a image idol (teraphim) to but a face of the legion to help distinguish with one of the legion .
Rachel used those kind idol images that she robbed from her father to also put a face on the legion as workers with familiar spirits .
Catholisicim has over 3,500 workers with familiar spirits that make up the legion and adding more and more as time increases as that they call patron saints.
