1 Peter 3:18 For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit. 19After being made alive, he went and made proclamation to the imprisoned spirits— 20to those who were disobedient long ago when God waited patiently in the days of Noah while the ark was being built.
Jude 61:6 And the angels who did not keep their positions of authority but abandoned their proper dwelling—these he has kept in darkness, bound with everlasting chains for judgment on the great Day.
Matthew 8:28 When he arrived at the other side in the region of the Gadarenes, two demon-possessed men coming from the tombs met him. They were so violent that no one could pass that way. 29“What do you want with us, Son of God?” they shouted. “Have you come here to torture us before the appointed time?” 30Some distance from them a large herd of pigs was feeding. 31The demons begged Jesus, “If you drive us out, send us into the herd of pigs.”
Did the demons worry about being imprisoned by Jesus? Was there a prison for demons at Peter's time?
