7 But Jephthah said to them, "Aren't you the ones who hated me and drove me from my father's house? Why do you come to me now when you're in trouble?" 8 "Because we need you," the elders replied. "If you lead us in battle against the Ammonites, we will make you ruler over all the people of Gilead." 9 Jephthah said to the elders, "Let me get this straight. If I come with you and if the Lord gives me victory over the Ammonites, will you really make me ruler over all the people?" 10 "The Lord is our witness," the elders replied. "We promise to do whatever you say." 11 So Jephthah went with the elders of Gilead, and the people made him their ruler and commander of the army. At Mizpah, in the presence of the Lord, Jephthah repeated what he had said to the elders.

12 Then Jephthah sent messengers to the king of Ammon, asking, "Why have you come out to fight against my land?" 13 The king of Ammon answered Jephthah's messengers, "When the Israelites came out of Egypt, they stole my land from the Arnon River to the Jabbok River and all the way to the Jordan. Now then, give back the land peaceably." 14 Jephthah sent this message back to the Ammonite king: 15 "This is what Jephthah says: Israel did not steal any land from Moab or Ammon. 16 When the people of Israel arrived at Kadesh on their journey from Egypt after crossing the Red Sea, 17 they sent messengers to the king of Edom asking for permission to pass through his land. But their request was denied. Then they asked the king of Moab for similar permission, but he wouldn't let them pass through either. So the people of Israel stayed in Kadesh. 18 "Finally, they went around Edom and Moab through the wilderness. They traveled along Moab's eastern border and camped on the other side of the Arnon River. But they never once crossed the Arnon River into Moab, for the Arnon was the border of Moab. 19 "Then Israel sent messengers to King Sihon of the Amorites, who ruled from Heshbon, asking for permission to cross through his land to get to their destination.

Commentary on Judges 11:1-11

(Read Judges 11:1-11)

Men ought not to be blamed for their parentage, so long as they by their personal merits roll away any reproach. God had forgiven Israel, therefore Jephthah will forgive. He speaks not with confidence of his success, knowing how justly God might suffer the Ammonites to prevail for the further punishment of Israel. Nor does he speak with any confidence at all in himself. If he succeed, it is the Lord delivers them into his hand; he thereby reminds his countrymen to look up to God as the Giver of victory. The same question as here, in fact, is put to those who desire salvation by Christ. If he save you, will ye be willing that he shall rule you? On no other terms will he save you. If he make you happy, shall he make you holy? If he be your helper, shall he be your Head? Jephthah, to obtain a little worldly honour, was willing to expose his life: shall we be discouraged in our Christian warfare by the difficulties we may meet with, when Christ has promised a crown of life to him that overcometh?

Commentary on Judges 11:12-28

(Read Judges 11:12-28)

One instance of the honour and respect we owe to God, as our God, is, rightly to employ what he gives us to possess. Receive it from him, use it for him, and part with it when he calls for it. The whole of this message shows that Jephthah was well acquainted with the books of Moses. His argument was clear, and his demand reasonable. Those who possess the most courageous faith, will be the most disposed for peace, and the readiest to make advances to obtain; but rapacity and ambition often cloak their designs under a plea of equity, and render peaceful endeavours of no avail.
