Judges 11:29-31

Living Bible

²⁹ At that time the Spirit of the Lord came upon Jephthah, and he led his army across the land of Gilead and Manasseh, past Mizpah in Gilead, and attacked the army of Ammon. ^30-31 Meanwhile Jephthah had vowed to the Lord that if God would help Israel conquer the Ammonites, then when he returned home in peace, the first person coming out of his house to meet him would be sacrificed as a burnt offering to the Lord!
