Secrets of Enoch (2 Enoch, Slavonic Enoch) 37:1
And God called one of His greatest angels, terrible and awful, and placed him by me, and the appearance of that angel was like snow, and his hands were like ice; he had a very cold appearance, and my face was chilled because I could not endure the fear of the Lord; just as it is not possible to endure the mighty fire and heat of the sun, and the frost of the air.
