One opinion among commentators is that after she mourned for her virginity in light of the Biblical commandment to "be fruitful and multiply", which she would now no longer be able to fulfill, Jephthah killed his daughter in an act of human sacrifice.
[5] Jephthah's daughter was not given a central role in many pre-medieval texts: the major exception was the first-century Liber Antiquitatum Biblicarum of "Pseudo-Philo", which devoted an entire chapter to her (and gave her the name of "Seila").
[6] In a letter to his lover Héloïse d'Argenteuil, Abelard also portrayed Seila as a model for monastic women who devote their whole lives to God.
[6] In the medieval period, some Jewish communities refrained from drinking water from wells and rivers for a few hours at four key times of the year, a custom called the tekufah.
[7] In the field of Jewish exegesis, the work titled Dirshuni: Contemporary Women's Midrash names Jephthah's daughter as "Tannot" (or "Tanot") and appears in various chapters.
