Judges 11:30-31, 35

Jephthah made a promise to the LORD, saying, “If you will hand over the Ammonites to me, I will give you as a burnt offering the first thing that comes out of my house to meet me when I return from the victory. It will be the LORD’s.”

When Jephthah saw his daughter, he tore his clothes to show his sorrow. He said, “My daughter! You have made me so sad because I made a promise to the LORD, and I cannot break it!”
