'Foul' in the Bible

when all at once, there in their synagogue, a man under the power of a foul spirit screamed out:

So the foul spirit, after throwing the man into convulsions, came out of him with a loud cry.

And all were amazed and awe-struck, so they began to ask one another, "What does this mean? Here is a new sort of teaching--and a tone of authority! And even to foul spirits he issues orders and they obey him!"

And the foul spirits, whenever they saw Him, threw themselves down at His feet, screaming out: "You are the Son of God."

This was because they said, "He is possessed by a foul spirit."

At once, on His landing, there came from the tombs to meet Him a man possessed by a foul spirit.

For He had said to him, "Foul spirit, come out of the man."

He gave them leave; and the foul spirits came out and entered into the swine, and the herd--about 2,000 in number--rushed headlong down the cliff into the Lake and were drowned in the Lake.

Then summoning the Twelve to Him, He proceeded to send them out by twos, and gave them authority over the foul spirits.

Forthwith a woman whose little daughter was possessed by a foul spirit heard of Him, and came and flung herself at His feet.

Then Jesus, seeing that an increasing crowd was running towards Him, rebuked the foul spirit, and said to it, "Dumb and deaf spirit, *I* command you, come out of him and never enter into him again."
