And on the 10th heaven, Aravoth, I saw the view of the face of the Lord, like iron made burning hot in a fire and brought out, and it emits sparks and is incandescent. Thus even I saw the face of the Lord. But the face of the Lord is not to be talked about, it is so very marvelous and supremely awesome and supremely frightening. And who am I to give an account of the incomprehensible being of the Lord, and of his face, so extremely strange and indescribable?… Who can give an account of his beautiful appearance, never changing and indescribable, and his great glory? And I feel down flat and did obeisance to the Lord.
