Ezekiel 39:1, 11, 15

“And you, son of man, prophesy against Gog and say, Thus says the Lord GOD: Behold, I am against you, O Gog, chief prince of Meshech and Tubal.

“On that day I will give to Gog a place for burial in Israel, the Valley of the Travelers, east of the sea. It will block the travelers, for there Gog and all his multitude will be buried. It will be called the Valley of Hamon-gog.

And when these travel through the land and anyone sees a human bone, then he shall set up a sign by it, till the buriers have buried it in the Valley of Hamon-gog.
