Description of a class of angels
1 R. Ishmael said: Metatron, the Angel, the Prince of the Presence, said to me: Each one of thetaa nas seventy names corresponding to the seventy tongues of the world. And all of them are (based) upon the name of the Holy One, blessed be He. And every several name is written with a flaming styleupon the Fearful Crown (Kether Nora) which is on the head of the high and exalted King.
2 And from each one of them there go forth sparks and lightnings. And each one of them is beset with horns of splendour round about. From each one lights are shining forth, and each one is surrounded by tents of brilliance so that not even the Seraphim and the Chayyoth who are greater than all the children of heaven are able to behold them.
