Jeremiah 49:3

Howl, O Heshbon, at that time occupied by the Ammonites, for Ai is spoiled, had already been subdued by the invaders; cry, ye daughters of Rabbah, the towns and villages near the capital, gird you with sackcloth, in token of deep mourning; lament and run to and fro by the hedges, in the fenced encampment, such as were quickly erected out in the open fields, since the cities no longer offered any protection; for their king shall go into captivity, in this case their idol Melchom, with whom the heathen king was pleased to identify himself, and his priests and his princes together. Cf Amos 1:15. The reason for the Lord's punishment upon Ammon is now set forth, as the prophet pictures the pride, the stubbornness, and the security of its inhabitants.
