1 Peter 3:20
to those who were disobedient long ago when God waited patiently in the days of Noah while the ark was being built. In it only a few people, a mere eight souls, were saved through water — the connection to Noah's flood (Genesis 6-8) establishes that the spirits-in-prison passage refers to those who 'formerly disobeyed' (apeitheo), likely the antediluvian generation. The salvation of 'eight souls' through the ark foreshadows believers' salvation.
