1 Peter 3

18 Jesus died because of sins, once and for all, the one who is completely true and good and right died for those who are bad,*3:18. Literally, "the right for the unright." In this verse the inevitable results of sin are made clear through the death of Jesus. He experienced the consequences of sin in the most dramatic and conclusive way possible, and also proved it was not God who kills, but that sin itself brings its inevitable fatal result (see Romans 6:23). so that he could bring you to God. He was put to death in the body, but he came to life in the spirit.

19 He went to speak to those "imprisoned"*3:19. Or "imprisoned souls." There has been much debate over this phrase. The same word used for "souls" should note the same word is used for the eight people in verse 20. Some understand those "imprisoned" as those people at the time of the Flood who were "held captive" by their sinfulness (see Genesis 6:5).
