Judges 11:18-40

Then they went through the wilderness and around the land of Edom and the land of Moab, and came to the east side of the land of Moab, and they camped beyond the Arnon; but they did not enter the territory of Moab, for the Arnon was the border of Moab. And Israel sent messengers to Sihon king of the Amorites, the king of Heshbon, and Israel said to him, “Please let us pass through your land to our place.” But Sihon did not trust Israel to pass through his territory; so Sihon gathered all his people and camped in Jahaz and fought with Israel. The LORD, the God of Israel, gave Sihon and all his people into the hand of Israel, and they defeated them; so Israel possessed all the land of the Amorites, the inhabitants of that country. So they possessed all the territory of the Amorites, from the Arnon as far as the Jabbok, and from the wilderness as far as the Jordan. Since now the LORD, the God of Israel, drove out the Amorites from before His people Israel, are you then to possess it? Do you not possess what Chemosh your god gives you to possess? So whatever the LORD our God has driven out before us, we will possess it. Now are you any better than Balak the son of Zippor, king of Moab? Did he ever strive with Israel, or did he ever fight against them? While Israel lived in Heshbon and its villages, and in Aroer and its villages, and in all the cities that are on the banks of the Arnon, three hundred years, why did you not recover them within that time? I therefore have not sinned against you, but you are doing me wrong by making war against me; may the LORD, the Judge, judge today between the sons of Israel and the sons of Ammon.’ ” But the king of the sons of Ammon disregarded the message which Jephthah sent him. Now the Spirit of the LORD came upon Jephthah, so that he passed through Gilead and Manasseh; then he passed through Mizpah of Gilead, and from Mizpah of Gilead he went on to the sons of Ammon. Jephthah made a vow to the LORD and said, “If You will indeed give the sons of Ammon into my hand, then it shall be that whatever comes out of the doors of my house to meet me when I return in peace from the sons of Ammon, it shall be the LORD’S, and I will offer it up as a burnt offering.” So Jephthah crossed over to the sons of Ammon to fight against them; and the LORD gave them into his hand. He struck them with a very great slaughter from Aroer to the entrance of Minnith, twenty cities, and as far as Abel-keramim. So the sons of Ammon were subdued before the sons of Israel. When Jephthah came to his house at Mizpah, behold, his daughter was coming out to meet him with tambourines and with dancing. Now she was his one and only child; besides her he had no son or daughter. When he saw her, he tore his clothes and said, “Alas, my daughter! You have brought me very low, and you are among those who trouble me; for I have given my word to the LORD, and I cannot take it back.” So she said to him, “My father, you have given your word to the LORD; do to me as you have said, since the LORD has avenged you of your enemies, the sons of Ammon.” She said to her father, “Let this thing be done for me; let me alone two months, that I may go to the mountains and weep because of my virginity, I and my companions.” Then he said, “Go.” So he sent her away for two months; and she left with her companions, and wept on the mountains because of her virginity. At the end of two months she returned to her father, who did to her according to the vow which he had made; and she had no relations with a man. Thus it became a custom in Israel, that the daughters of Israel went yearly to commemorate the daughter of Jephthah the Gileadite four days in the year.
