Charles Ellicott Commentary Jeremiah 48:28

"O ye inhabitants of Moab, leave the cities, and dwell in the rock; and be like the dove that maketh her nest over the mouth of the abyss." — Jeremiah 48:28 (ASV)

O ye that dwell in Moab ... —The general thought is the same as in Jeremiah 48:6; Jeremiah 48:9, but is more vivid as being more specific. The Moabites are to leave their cities and take refuge in the caves, always in Palestine the asylum of fugitives (1 Samuel 13:6; 2 Samuel 17:9), as the wild dove flies to the clefts of the rock (Song of Solomon 2:14).
