Ezekiel 38:16, 23

and you will attack my people Israel, covering their land like a cloud. At that time in the distant future, I will bring you against my land as everyone watches, and my holiness will be displayed by what happens to you, Gog. Then all the nations will know that I am the LORD.

In this way, I will show my greatness and holiness, and I will make myself known to all the nations of the world. Then they will know that I am the LORD.
