Peter and Jude say that the sons of God who committed this transgression were imprisoned under the earth—in other words, they’re doing time in hell—until the last days. They’ll be part of God’s final judgment, something the Bible calls the “Day of the Lord.” Peter and Jude’s sources are well-known to Bible scholars. One of them was a book called 1 Enoch. It was popular with Jews of Jesus’ day and with Christians in the early church, even though it wasn’t considered sacred and inspired. But Peter and Jude thought some of that content was important enough to include in the letters they wrote.
