Then the people of Ephraim asked Gideon, "Why have you treated us this way? Why didn't you send for us when you first went out to fight the Midianites?" And they argued heatedly with Gideon.
But Gideon replied, "What have I done compared to you? Aren't the last grapes of Ephraim's harvest better than the entire crop of my little clan of Abiezer?
God gave you victory over Oreb and Zeeb, the generals of the Midianite army. What have I done compared to that?" When the men of Ephraim heard Gideon's answer, they were no longer angry.
Gideon then crossed the Jordan River with his three hundred men, and though they were exhausted, they continued to chase the enemy.
When they reached Succoth, Gideon asked the leaders of the town, "Will you please give my warriors some food? They are very tired. I am chasing Zebah and Zalmunna, the kings of Midian."
But the leaders of Succoth replied, "You haven't caught Zebah and Zalmunna yet. Catch them first, and then we will feed your warriors."
So Gideon said, "After the LORD gives me victory over Zebah and Zalmunna, I will return and tear your flesh with the thorns and briers of the wilderness."
From there Gideon went up to Peniel and asked for food, but he got the same answer.
