Jeremiah 49:3

Howl, O Heshbon— That is, "When Ai, a city of Ammon, is destroyed, it is time for Heshbon, the chief city of Moab, to lament her danger." The author of the Observations remarks, that the phrase, Run to and fro by the hedges, should rather be understood and rendered, Run—by the garden-walls. Their places of burial in the east are without their cities, as well as their gardens; and consequently their going to them must often be by the garden-walls. The ancient warriors of distinction who were slain in battle, were wont to be carried to the sepulchres of their fathers, as appears from the cases of Josiah, Ahab, and Asahel; and they often go, to weep over the graves of those whom they would honour, especially at first; Observations which, put together, sufficiently account for this passage.
