Jephthahs daughter

A few weeks ago i mused on what Jephthah did with his daughter when he returned from war, as i prepared to teach it at Sunday School. Today i might have come across a clue as my daily readings took me to Judges 12:8-14.

Everyone is mentioned in relation to his many (many) children and grandchildren. I wonder if this is in contrast to Jephthah, who could have no grandchildren because he'd pledged his daughter to perpetual virginity. Jephthah had just stopped judging after the shibboleth war with the Ephraimites.

Not a huge step in Biblical history, but interesting to me nonetheless!
