Thematic Bible: Jephthah, of his daughter

Jephthah made a vow to the Lord, saying, "If you really do hand the Ammonites over to me, then whoever is the first to come through the doors of my house to meet me when I return safely from fighting the Ammonites -- he will belong to the Lord and I will offer him up as a burnt sacrifice."

When Jephthah came home to Mizpah, there was his daughter hurrying out to meet him, dancing to the rhythm of tambourines. She was his only child; except for her he had no son or daughter. When he saw her, he ripped his clothes and said, "Oh no! My daughter! You have completely ruined me! You have brought me disaster! I made an oath to the Lord, and I cannot break it." She said to him, "My father, since you made an oath to the Lord, do to me as you promised. After all, the Lord vindicated you before your enemies, the Ammonites." read more.
She then said to her father, "Please grant me this one wish. For two months allow me to walk through the hills with my friends and mourn my virginity." He said, "You may go." He permitted her to leave for two months. She went with her friends and mourned her virginity as she walked through the hills. After two months she returned to her father, and he did to her as he had vowed. She died a virgin. Her tragic death gave rise to a custom in Israel. Every year Israelite women commemorate the daughter of Jephthah the Gileadite for four days.
