Adam Clarke on Ezekiel 39:11

The valley of the passengers on the east of the sea - That is, of Gennesareth, according to the Targum. The valley near this lake or sea is called the Valley of the Passengers, because it was a great road by which the merchants and traders from Syria and other eastern countries went into Egypt; see Gen 37:17, Gen 37:25. See Calmet here.

There shall they bury Gog and all his multitude - Some read, "There shall they bury Gog, that is, all his multitude." Not Gog, or Antiochus himself, for he was not in this battle; but his generals, captains, and soldiers, by whom he was represented. As to Hamon-gog, we know no valley of this name but here. But we may understand the words thus: the place where this great slaughter was, and where the multitudes of the slain were buried, might be better called Hamon-gog, the valley of the multitude of God, than the valley of passengers; for so great was the carnage there, that the way of the passengers shall be stopped by it.
