And behold, a shining red cloud descended from the mountains into the valley above the bush, and from it a violent flash of lightning struck the bush with a thunderous noise. And lo, a big serpent fled hissing from the bush and with open jaws took the direction towards Cain, and he was terrified. But lo, the flashes of lightning followed it and drove it with great speed into the hot sand of the vast desert. When it had vanished completely from his sight, Cain turned again to the bush and silently thanked God for so graciously saving him from the greatest of all dangers. – The Household of God, Book 1, Chapter 21, Paragraph 7
