Isaías 31:8

8 "Assyria will fall by no human sword; a sword, not of mortals, will devour them. They will flee before the sword and their young men will be put to forced labor.

8 Then the Assyrian will come down by the sword, but not of man; the sword, not of men, will be the cause of his destruction: and he will go in flight from the sword, and his young men will be put to forced work.
