Jeremiah 48:8

All the cities, the valley, and the plateau-in short, the whole nation-would fall before the coming enemy, as Yahweh predicted. "The valley" was the Jordan Valley in which Moab had holdings, and "the plateau" refers to the tableland from Aroer northward to Heshbon (cf. Joshua 13:15-17). Most of Moab stood on this fertile plateau.

"For defense, Moab had towering cliffs, and for wealth, her enormous flocks of sheep [cf. 2 Kings 3:4]; riches that were self-renewing. But the shelter of these things had bred more complacency than character." [Note: Kidner, p. 142.]
