Book of Enoch (1 Enoch) 56:5
And in those days the angels shall return And hurl themselves to the east upon the Parthians and Medes: They shall stir up the kings, so that a spirit of unrest shall come upon them, And they shall rouse them from their thrones, That they may break forth as lions from their lairs, And as hungry wolves among their flocks.
Background and history of Book of Enoch (1 Enoch), and issues with this book.
R. H. Charles, The Book of Enoch (London: SPCK, 1917), public domain. The verse text is the English Wikisource transcription of that translation. Charles’s editorial signs are kept. He rearranges some verses in chapters 5, 39, 90, 91, and 106, so those chapters are not a straight 1, 2, 3 sequence.
