But the LORD, the God of Israel, gave his people victory over King Sihon. So Israel took control of all the land of the Amorites, who lived in that region,
from the Arnon River to the Jabbok River, and from the wilderness to the Jordan."
"So you see, it was the LORD, the God of Israel, who took away the land from the Amorites and gave it to Israel. Why, then, should we give it to you?
You keep whatever your god Chemosh gives you, and we will keep whatever the LORD our God gives us.
Are you any better than Balak son of Zippor, king of Moab? Did he try to make a case against Israel for disputed land? Did he go to war? No, of course not.
But now after three hundred years you make an issue of this! Israel has been living here all this time, spread across the land from Heshbon to Aroer and in all the towns along the Arnon River. Why have you made no effort to recover it before now?
I have not sinned against you. Rather, you have wronged me by attacking me. Let the LORD, who is judge, decide today which of us is right -- Israel or Ammon."
But the king of Ammon paid no attention to Jephthah's message.
At that time the Spirit of the LORD came upon Jephthah, and he went throughout the land of Gilead and Manasseh, including Mizpah in Gilead, and led an army against the Ammonites.
And Jephthah made a vow to the LORD. He said, "If you give me victory over the Ammonites,
I will give to the LORD the first thing coming out of my house to greet me when I return in triumph. I will sacrifice it as a burnt offering."
