29 Then the spirit of the Lord came on Jephthah, and he went through Gilead and Manasseh, and came to Mizpeh of Gilead; and from Mizpeh of Gilead he went over to the children of Ammon.

30 And Jephthah took an oath to the Lord, and said, If you will give the children of Ammon into my hands,

31 Then whoever comes out from the door of my house, meeting me when I come back in peace from the children of Ammon, will be the Lord's and I will give him as a burned offering.
