Behold, therefore I will deliver thee to the men of the east for a possession, and they shall set their palaces in thee, and make their dwellings in thee: they shall eat thy fruit, and they shall drink thy milk.
Behold, therefore I will deliver thee to the men of the east - literally, children of the east, the nomad tribes of Arabia Deserta, east of the Jordan and the Dead Sea.
They shall set their palaces in thee - their nomadic encampments or folds, surrounded with mud walls, are so called in irony. Where thy "palaces" once stood, there shall their very different "palaces" stand. Fulfilled after the ravaging of their region by Nebuchadnezzar shortly after the destruction of Jerusalem (cf. Ezekiel 21:22; Jeremiah 49:1-28).

And the Ammonites a couching place for flocks - i:e., the Ammonite region is to be a "couching place for flocks," namely, of the Arabs. The "camels," being the chief beast of burden of the Chaldeans, is put first, as their invasion was to prepare the Ammonite land for the Arab "flocks." Instead of busy men, there shall be 'still and couching flocks.'
