1 Enoch 21:10

7 And from thence I went to another place, which was still more horrible than the former, and I saw a horrible thing: a great fire there which burnt and blazed, and the place was cleft as far as the abyss, being full of great descending columns of fire: neither its extent or magnitude could I see, nor could I conjecture. 8 Then I said: 'How fearful is the place and how terrible to look upon!' 9 Then Uriel answered me, one of the holy angels who was with me, and said unto me: 'Enoch, why hast thou such fear and affright?' And I answered: 'Because of this fearful place, and because of the spectacle of the pain.' 10 And he said ⌈⌈unto me⌉⌉: 'This place is the prison of the angels, and here they will be imprisoned for ever.'

New Testament

1 Peter 3:19

15 But set Christ apart as Lord in your hearts and always be ready to give an answer to anyone who asks about the hope you possess. 16 Yet do it with courtesy and respect, keeping a good conscience, so that those who slander your good conduct in Christ may be put to shame when they accuse you. 17 For it is better to suffer for doing good, if God wills it, than for doing evil. 18 Because Christ also suffered once for sins, the just for the unjust, to bring you to God, by being put to death in the flesh but by being made alive in the spirit. 19 In it he went and preached to the spirits in prison, 20 after they were disobedient long ago when God patiently waited in the days of Noah as an ark was being constructed. In the ark a few, that is eight souls, were delivered through water. 21 And this prefigured baptism, which now saves you—not the washing off of physical dirt but the pledge of a good conscience to God—through the resurrection of Jesus Christ, 22 who went into heaven and is at the right hand of God with angels and authorities and powers subject to him.
