“Tell the Israelites this: If there are people, men or women, who want to make a vow dedicating themselves to the Lord as Nazirites for a time, this is what they must do:
She made a special promise to God and said, “Lord All-Powerful, you can see how sad I am. Remember me. Don’t forget me. If you will give me a son, I will give him to you. He will be yours his whole life, and as a Nazirite, he will not drink wine or strong drink, and no one will ever cut his hair.”
At the end of two months, Jephthah’s daughter returned to her father, and Jephthah did what he had promised. His daughter never had sexual relations with anyone. So this became a custom in Israel.
Then the Israelites made a special promise to the Lord: “Please help us defeat these people. If you do this, we will give their cities to you. We will totally destroy them.”
