the evil spirit
1 Samuel 16:14
But the Spirit of the LORD departed from Saul, and an evil spirit from the LORD troubled him.
1 Samuel 16:16
Let our lord now command thy servants, which are before thee, to seek out a man, who is a cunning player on an harp: and it shall come to pass, when the evil spirit from God is upon thee, that he shall play with his hand, and thou shalt be well.
Saul
1 Samuel 18:10
And it came to pass on the morrow, that the evil spirit from God came upon Saul, and he prophesied in the midst of the house: and David played with his hand, as at other times: and there was a javelin in Saul's hand.
1 Samuel 18:11
And Saul cast the javelin; for he said, I will smite David even to the wall with it. And David avoided out of his presence twice.
Matthew 12:43-45
43
When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none.
44
Then he saith, I will return into my house from whence I came out; and when he is come, he findeth it empty, swept, and garnished.
45
Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.
Luke 11:24-26
24
When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out.
25
And when he cometh, he findeth it swept and garnished.
26
Then goeth he, and taketh to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first.
