Then the Lord God of Israel handed over Sihon and all his people to Israel, and they defeated them. So Israel took possession of the entire land of the Amorites who lived in that country.
They took possession of all the territory of the Amorites from the Arnon to the Jabbok and from the wilderness to the Jordan.
"The Lord God of Israel has now driven out the Amorites before His people Israel, but will you drive us out?
Isn't it true that you may possess whatever your god Chemosh drives out for you, and we may possess everything the Lord our God drives out before us?
Now are you any better than Balak son of Zippor, king of Moab? Did he ever contend with Israel or fight against them?
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?
I have not sinned against you, but you have wronged me by fighting against me. Let the Lord [who is] the Judge decide today between the Israelites and the Ammonites."
But the king of the Ammonites would not listen to Jephthah's message that he sent him.
The Spirit of the Lord came on Jephthah, who traveled through Gilead and Manasseh, and then through Mizpah of Gilead. He crossed over to the Ammonites from Mizpah of Gilead.
Jephthah made this vow to the Lord: "If You will hand over the Ammonites to me,
whatever comes out of the doors of my house to greet me when I return in peace from the Ammonites will belong to the Lord, and I will offer it as a burnt offering."
