'Possessed' in the Bible

Now when Jesus stepped out on land, He was met by a man from the city [of Gerasa] who was possessed with demons. For a long time he had worn no clothes, and was not living in a house, but among the tombs.

Those who had seen it told them how the man who had been demon-possessed had been healed.

Then all the people of the country of the Gerasenes and the surrounding district asked Him to leave them, because they were overwhelmed with fear. So Jesus got into the boat and returned [to the west side of the Sea of Galilee].
