2 Enoch

The men took me on to the fifth heaven and placed me, and there I saw many and countless soldiers, called Grigori, of human appearance, and their size (was) greater than that of great giants and their faces withered, and the silence of their mouths perpetual, and their was no service on the fifth heaven , and I said to the men who were with me:

Wherefore are these very withered and their faces melancholy, and their mouths silent, and (wherefore) is there no service on this heaven ?
