1 Peter 3:18-20

18For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but made alive by the Spirit: 19By whom also he went and preached to the spirits in prison; 20Who at one time were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was preparing, in which few, that is, eight souls were saved by water.
