Then the Spirit of the Lord came upon Jephthah, and he passed over
Gilead, and Manasseh, and passed over Mizpeh of Gilead, and from Mizpeh
of Gilead he passed over unto the children of Ammon.
And Jephthah vowed a vow unto the Lord, and said, If thou shalt without
fail deliver the children of Ammon into mine 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.
So Jephthah passed over unto the children of Ammon to fight against them;
and the Lord delivered them into his hands. And he smote them from Aroer,
even till thou come to Minnith, even twenty cities, and unto the plain of
the vineyards, with a very great slaughter. Thus the children of Ammon
were subdued before the children of Israel.
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; beside her he had neither son nor daughter. Judges xi, 29-34.
