Judges 11:32

So Jephthah passed over unto the children of Ammon, to fight
against them
As in ( Judges 11:29 ) , after he had made the above vow:

and the Lord delivered them into his hands;
when both armies met and engaged, victory was on the side of Jephthah; the Lord being with him, and giving him success, to where all is justly ascribed.
