“I will make Rabbah
A pasture for camels.
Ammon shall be
A fold for flocks.
Then you will know
That I am Yahweh.”
Rabbah was the capital of Ammon. Thus the capital city would become a pasture for camels. The current capital of Jordan is Amman where Rabbah once was. Ammon would just become a place for animals to graze. They would learn that Yahweh was in charge.
