Bede — on Rev 8:7 (Commentary on Revelation)

“And there was hail and fire, mixed with blood, etc. It is proclaimed by the voice of preachers that the punishment of hell is due for bloodstained deeds, saying: "From excessive heat they will pass by the waters of snow" (Job 24). The name blood can also mean the death of the spiritual soul itself. Tyconius interprets this verse thus: "the wrath of God was made, which had in it the death of many."”
