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 Genesis 37:17, Genesis 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. See the text.
The prophet pictures to himself some imaginary valley (compare Zechariah 14:5) at the “east of the sea,” the Dead Sea, a place frightful in its physical character, and admonitory of past judgments. He calls it “the valley of the passengers” (or, passers-by), because they who there lie buried were but as a passing cloud. In Ezekiel 39:11-15 there is a play upon words - there were “passengers” to be buried, “passengers” to walk over their graves, “passengers” to bury them; (or, a play upon the treble meaning of passing in (invading), passing by, and passing through.)
Stop the noses - The word thus rendered occurs only once more in Scripture Deuteronomy 25:4 where it is rendered muzzle. See Isaiah 34:3.
Hamon-gog - See the margin, compare Ezekiel 39:16.
