3. Heshbon . . . Ai--Nebuchadnezzar, coming from the north, first
attacked Ammon, then its brother and neighbor, Moab. As Ai of Ammon had
already suffered destruction, Heshbon of Moab being near it might well
fear the same fate.
hedges--Their cities being destroyed, the outcasts have no place of
shelter save behind the "hedges" of vineyards and gardens; or else the
enclosures of their villages.
their king--Melchom, the idol, as the mention of "his priests" shows
(compare
Jer 48:7).
