Reading 1 Jgs 11:29-39a
The Spirit of the LORD came upon Jephthah. He passed through Gilead and Manasseh, and through Mizpah-Gilead as well, and from there he went on to the Ammonites. Jephthah made a vow to the LORD. "If you deliver the Ammonites into my power," he said, "whoever comes out of the doors of my house to meet me when I return in triumph from the Ammonites shall belong to the LORD. I shall offer him up as a burnt offering."
