Judges 11:33
Brenton's English Septuagint · Berean Standard Bible
And he smote them from Aroer till [one] comes to Arnon, in number twenty cities, and as far as Ebelcharmim, with a very great destruction: and the children of Ammon were straitened before the children of Israel.
With a great blow he devastated twenty cities from Aroer to the vicinity of Minnith, as far as Abel-keramim. So the Ammonites were subdued before the Israelites.
