Samuel
Judges 11:33BSB·traditional attribution

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.

Matthew Henry Presbyterian @wholebiblehenry

We have here Jephthah triumphing in a glorious victory, but, as an alloy to his joy, troubled and distressed by an unadvised vow. I. Jephthah's victory was clear, and shines very brightly, both to his honour and to the honour of God, his in pleading and God's in owning a righteous cause. 1. God gave him an excellent spirit, and he improved it bravely, Jdg 11:29.

And it came to pass, when he saw her,.... She being the first person that presented to his view, as she was at the head of the virgins with their timbrels and dances: that he rent his clothes; as was the usual manner, when anything calamitous and distressing happened; see Gen 37:34.

HE OVERCOMES THE AMMONITES. (Jdg 11:32-33) Jephthah passed over unto the children of Ammon . . . and the Lord delivered them into his hands--He met and engaged them at Aroer, a town in the tribe of Gad, upon the Arnon.
