Judges 11:39

39After the two months, she returned to her father, and he did to her as he had vowed. And she was a virgin.

39And after the ende of two moneths, she turned againe vnto her father, who did with her according to his vowe which he had vowed, and she had knowen no man. and it was a custome in Israel:

39At the end of two months, she returned to her father, who did with her according to his vow which he had vowed. She was a virgin. It became a custom in Israel

39After the two months were over, she returned to her father. He did to her just what he had promised to do. And she was a virgin.

So that became a practice in Israel.

39After two months she returned to her father, Jephthah. He did what he had promised to the Lord. His daughter never married.

39and it comes to pass at the end of two months that she turns back to her father, and he does to her his vow which he has vowed, and she did not know a man; and it is a statute in Israel:
