While Israel lived 300 years in Heshbon and its villages, in Aroer and its villages, and in all the cities that are on the banks of the Arnon, why didn’t you take them back at that time?

He defeated 20 of their cities with a great slaughter from Aroer all the way to the entrance of Minnith and to Abel-keramim. So the Ammonites were subdued before the Israelites.
