'Unclean' in the Bible
Just then there was a man in their synagogue with an unclean spirit; and he cried out [terribly from the depths of his throat],
The unclean spirit threw the man into convulsions, and screeching with a loud voice, came out of him.
They were all so amazed that they debated and questioned each other, saying, “What is this? A new teaching with authority! He commands even the unclean spirits (demons), and they obey Him.”
Whenever the unclean spirits saw Him, they fell down before Him and screamed out, “You are the Son of God!”
[Jesus said this] because the scribes and Pharisees were [attributing His miracles to Satan by] saying, “He has an unclean spirit.”
When Jesus got out of the boat, immediately a man from the tombs with an unclean spirit met Him,
For Jesus had been saying to him, “Come out of the man, you unclean spirit!”
Jesus gave them permission. And the unclean spirits came out [of the man] and entered the pigs. The herd, numbering about two thousand, rushed down the steep bank into the sea; and they were drowned [one after the other] in the sea.
As He was stepping into the boat, the [Gentile] man who had been demon-possessed was begging with Him [asking] that he might go with Him [as a disciple].
And He called the twelve [disciples] and began to send them out [as His special messengers] two by two, and gave them authority and power over the unclean spirits.
And they were casting out many demons and were anointing with oil many who were sick, and healing them.
there is nothing outside a man [such as food] which by going into him can defile him [morally or spiritually]; but the things which come out of [the heart of] a man are what defile and dishonor him.
And He said to them, “Are you, too, so foolish and lacking in understanding? Do you not understand that whatever goes into the man from outside cannot defile and dishonor him,
And He said, “Whatever comes from [the heart of] a man, that is what defiles and dishonors him.
All these evil things [schemes and desires] come from within and defile and dishonor the man.”
Instead, after hearing about Him, a woman whose little daughter had an unclean spirit immediately came and fell at His feet.
When Jesus saw that a crowd was rapidly gathering [around them], He rebuked the unclean spirit, saying to it, “You deaf and mute spirit, I command you, come out of him and never enter him again!”
