Numbers 21:26-31

²⁶Heshbon was the capital of Sihon, king of the Amorites, who had fought against the previous king of Moab and had taken from him all his land as far as the Arnon River.

²⁷That's why the old songwriters wrote: “Come to Heshbon and have it be rebuilt; restore the town of Sihon!

²⁸For a fire blazed out from Heshbon, a flame from the town of Sihon. It burned up Ar in Moab where the rulers live on the high places of Arnon.

²⁹What a disaster you face, Moab! You are all going to die, people of Chemosh! You handed over your sons as exiles and your daughters as prisoners to Sihon, king of the Amorites.

³⁰But now we have defeated the Amorites! Heshbon's rule has been destroyed all the way to Dibon. We wiped them out all the way to Nophah and on to Medeba.”

³¹The Israelites occupied the country of the Amorites.
