Ezekiel 38:21-23

21I will summon a sword against Gog on all my mountains, declares the Sovereign LORD . Every man’s sword will be against his brother. 22I will execute judgment on him with plague and bloodshed; I will pour down torrents of rain, hailstones and burning sulfur on him and on his troops and on the many nations with him. 23And so I will show my greatness and my holiness, and I will make myself known in the sight of many nations. Then they will know that I am the LORD .’
