Jephthah assembled all the men of Gilead and they fought with Ephraim. The men of Gilead defeated Ephraim, because the Ephraimites insulted them, saying, "You Gileadites are refugees in Ephraim, living within Ephraim's and Manasseh's territory."

The Lord's spirit empowered Jephthah. He passed through Gilead and Manasseh and went to Mizpah in Gilead. From there he approached the Ammonites.

Gideon said to him, "But Lord, how can I deliver Israel? Just look! My clan is the weakest in Manasseh, and I am the youngest in my family."

He sent messengers throughout Manasseh and summoned them to follow him as well. He also sent messengers throughout Asher, Zebulun, and Naphtali, and they came up to meet him.

Israelites from Naphtali, Asher, and Manasseh answered the call and chased the Midianites.

The men of Manasseh did not conquer Beth Shan, Taanach, or their surrounding towns. Nor did they conquer the people living in Dor, Ibleam, Megiddo or their surrounding towns. The Canaanites managed to remain in those areas.
