Therefore he says, Awake you that sleep, and arise from the dead, and Christ shall give you light.
All Commentaries on Ephesians 5:14 Go To Ephesians 5
Jerome
AD 420
The one who is content with a simple answer will say indeed that Paul must have read this phrase in some arcane prophet or in the writings called apocryphal. He then brought the text into the open, as he manifestly does in other places—not to substantiate the apocryphal texts but in the same way that he makes use of verses elsewhere from Aratus, Epimenides and Menander to substantiate what he says on other occasions…. Someone less content with this simple answer might argue that the apostle said this as an exhortation to penitence. It is as if he were assuming the voice of the Holy Spirit. For my part, scanty as my knowledge is, I have nowhere found this written after diligently scouring all the editions of the ancient Scriptures and the texts of the Hebrews themselves. .
