1 Peter 3:19-21

New Catholic Bible

¹⁹ In the spirit^[a] also he went to preach to the spirits in prison, ²⁰ those who had refused to obey long ago while God waited patiently in the days of Noah during the building of the ark. In it only a few persons, eight in all, were saved through water.

²¹ This water prefigured Baptism, which now saves you. It does so not by the washing away of dirt from the body but by the pledge of a good conscience given to God through the resurrection of Jesus Christ.
