Judges 11:39-40

International Children’s Bible

³⁹ After two months she returned to her father. Jephthah did to her what he promised to the Lord. Now Jephthah’s daughter had never had a husband.

So this became a custom in Israel. ⁴⁰ Every year the women of Israel would go out for four days. They did this to remember the daughter of Jephthah from Gilead.
