Judges 11:30:⁠—

“And Jephthah vowed a vow unto the Lord, and said, If thou shalt without fail deliver the children of Ammon into my hands, then it shall be, that whatsoever cometh forth of the doors of my house to meet me, when I return in peace from the children of Ammon, shall surely be the Lord’s, and I will offer it up for a burnt-offering⁠ ⁠… And Jephthah came to Mizpeh unto his house, and, behold, his daughter came out to meet him with timbrels and with dances; and she was his only child: besides her he had neither son nor daughter.”
