1 Enoch

And I saw till that in this manner thirty-five shepherds undertook the pasturing (of the sheep) , and they severally completed their periods as did the first; and others received them into their hands, to pasture them for their period, each shepherd in his own period.

And after that I saw in my vision all the birds of heaven coming, the eagles, the vultures, the kites, the ravens; but the eagles led all the birds; and they began to devour those sheep, and to pick out their eyes and to devour their flesh.
