1 Peter 3:18–20

18 For Christ also diedh for sins once for all, the righteous for the unrighteous, that he might bring us to God, being put to death in the flesh but made alive in the spirit; 19 in which he went and preached to the spirits in prison, 20 who formerly did not obey, when God’s patience waited in the days of Noah, during the building of the ark, in which a few, that is, eight persons, were saved through water.
