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. 20 But King Sihon didn't trust Israel to pass through his land. Instead, he mobilized his army at Jahaz and attacked them. 21 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, 22 from the Arnon River to the Jabbok River, and from the eastern wilderness to the Jordan. 23 "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 back to you? 24 You keep whatever your god Chemosh gives you, and we will keep whatever the Lord our God gives us. 25 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 against them? 26 "Israel has been living here for 300 years, inhabiting Heshbon and its surrounding settlements, all the way to Aroer and its settlements, and in all the towns along the Arnon River. Why have you made no effort to recover it before now? 27 Therefore, 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." 28 But the king of Ammon paid no attention to Jephthah's message.

29 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 from there he led an army against the Ammonites. 30 And Jephthah made a vow to the Lord . He said, "If you give me victory over the Ammonites, 31 I will give to the Lord whatever comes out of my house to meet me when I return in triumph. I will sacrifice it as a burnt offering." 32 So Jephthah led his army against the Ammonites, and the Lord gave him victory. 33 He crushed the Ammonites, devastating about twenty towns from Aroer to an area near Minnith and as far away as Abel-keramim. In this way Israel defeated the Ammonites. 34 When Jephthah returned home to Mizpah, his daughter came out to meet him, playing on a tambourine and dancing for joy. She was his one and only child; he had no other sons or daughters. 35 When he saw her, he tore his clothes in anguish. "Oh, my daughter!" he cried out. "You have completely destroyed me! You've brought disaster on me! For I have made a vow to the Lord, and I cannot take it back." 36 And she said, "Father, if you have made a vow to the Lord, you must do to me what you have vowed, for the Lord has given you a great victory over your enemies, the Ammonites. 37 But first let me do this one thing: Let me go up and roam in the hills and weep with my friends for two months, because I will die a virgin." 38 "You may go," Jephthah said. And he sent her away for two months. She and her friends went into the hills and wept because she would never have children. 39 When she returned home, her father kept the vow he had made, and she died a virgin. So it has become a custom in Israel 40 for young Israelite women to go away for four days each year to lament the fate of Jephthah's daughter.

Matthew Henry's Commentary on Judges 11:12-40

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.

Commentary on Judges 11:29-40

(Read Judges 11:29-40)

Several important lessons are to be learned from Jephthah's vow. 1. There may be remainders of distrust and doubting, even in the hearts of true and great believers. 2. Our vows to God should not be as a purchase of the favour we desire, but to express gratitude to him. 3. We need to be very well-advised in making vows, lest we entangle ourselves. 4. What we have solemnly vowed to God, we must perform, if it be possible and lawful, though it be difficult and grievous to us. 5. It well becomes children, obediently and cheerfully to submit to their parents in the Lord. It is hard to say what Jephthah did in performance of his vow; but it is thought that he did not offer his daughter as a burnt-offering. Such a sacrifice would have been an abomination to the Lord; it is supposed she was obliged to remain unmarried, and apart from her family. Concerning this and some other such passages in the sacred history, about which learned men are divided and in doubt, we need not perplex ourselves; what is necessary to our salvation, thanks be to God, is plain enough. If the reader recollects the promise of Christ concerning the teaching of the Holy Spirit, and places himself under this heavenly Teacher, the Holy Ghost will guide to all truth in every passage, so far as it is needful to be understood.
