'Unclean Spirits' in the Bible

And summoning his twelve disciples he gave them power over unclean spirits, power to cast them out and also to heal every disease and every ailment.

Then they were all so amazed that they discussed it together, saying, "Whatever is this?" "It's new teaching with authority behind it!" "He orders even unclean spirits!" "Yes, and they obey him!"

And whenever the unclean spirits saw him they fell down before him, screaming, "You are the Son of God!"

And Jesus gave them leave. Then out came the unclean spirits and entered the swine, and the drove rushed down the steep slope into the sea (there were about two thousand of them) and in the sea they were drowned.

And summoning the twelve he proceeded to send them out two by two; he gave them power over the unclean spirits,

Afterwards he appeared at table to the eleven themselves and reproached them for their unbelief and dulness of mind, because they had not believed those who saw him risen from the dead. [But they excused themselves, saying, "This age of lawlessness and unbelief lies under the sway of Satan, who will not allow what lies under the unclean spirits to understand the truth and power of God; therefore," they said to Christ, "reveal your righteousness now." Christ answered them, "The term of years for Satan's power has now expired, but other terrors are at hand. I was delivered to death on behalf of sinners, that they might return to the truth and sin no more, that they might inherit that glory of righteousness which is spiritual and imperishable in heaven."]

Then amazement came over them all; they talked it over among themselves, saying, "What does this mean? He orders the unclean spirits with authority and power, and they come out!"

Those who were annoyed with unclean spirits also were healed.

Crowds gathered even from the towns round Jerusalem, bringing invalids and people troubled with unclean spirits, all of whom were healed.

For unclean spirits came screaming and shrieking out of many who had been possessed, and many paralytics and lame people were healed.
