“Then Israel sent messengers to Sihon king of the Amorites, who ruled in Heshbon, and said to him, ‘Let us pass through your country to our own place.’
Sihon, however, did not trust Israel to pass through his territory. He mustered all his troops and encamped at Jahaz and fought with Israel.
“Then the LORD, the God of Israel, gave Sihon and his whole army into Israel’s hands, and they defeated them. Israel took over all the land of the Amorites who lived in that country,
capturing all of it from the Arnon to the Jabbok and from the desert to the Jordan.
“Now since the LORD, the God of Israel, has driven the Amorites out before his people Israel, what right have you to take it over?
Will you not take what your god Chemosh gives you? Likewise, whatever the LORD our God has given us, we will possess.
Are you any better than Balak son of Zippor, king of Moab? Did he ever quarrel with Israel or fight with them?
For three hundred years Israel occupied Heshbon, Aroer, the surrounding settlements and all the towns along the Arnon. Why didn’t you retake them during that time?
I have not wronged you, but you are doing me wrong by waging war against me. Let the LORD, the Judge, decide the dispute this day between the Israelites and the Ammonites.”
The king of Ammon, however, paid no attention to the message Jephthah sent him.
Then the Spirit of the LORD came on Jephthah. He crossed Gilead and Manasseh, passed through Mizpah of Gilead, and from there he advanced against the Ammonites.
