Judges 11:30-32

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. {whatsoever...: Heb. that which cometh forth, which shall come forth} {and...: or, or I will offer it, etc} So Jephthah passed over unto the children of Ammon to fight against them; and the LORD delivered them into his hands.
