'Unclean' in the Bible
And there was in their synagogue a man with an unclean spirit, and he cried out,
and the unclean spirit having torn him, and having cried with a great voice, came forth out of him,
and they were all amazed, so as to reason among themselves, saying, 'What is this? what new teaching is this? that with authority also the unclean spirits he commandeth, and they obey him!'
and the unclean spirits, when they were seeing him, were falling down before him, and were crying, saying -- 'Thou art the Son of God;'
and he having come forth out of the boat, immediately there met him out of the tombs a man with an unclean spirit,
(for he said to him, 'Come forth, spirit unclean, out of the man,')
and immediately Jesus gave them leave, and having come forth, the unclean spirits did enter into the swine, and the herd did rush down the steep place to the sea -- and they were about two thousand -- and they were choked in the sea.
and he doth call near the twelve, and he began to send them forth two by two, and he was giving them power over the unclean spirits,
for a woman having heard about him, whose little daughter had an unclean spirit, having come, fell at his feet, --
Jesus having seen that a multitude doth run together, rebuked the unclean spirit, saying to it, 'Spirit -- dumb and deaf -- I charge thee, come forth out of him, and no more thou mayest enter into him;'
