What does Judges 11:36 mean?
The courage, respect, and submissiveness of Jephthah's daughter is almost as impressive as his apparent selfishness and folly. She has just learned of Jephthah's vow (Judges 11:30–31) about whatever came to greet him after his victory. As it happens, that was her (Judges 11:34). That, at the very least, means her father had promised to devote her entirely to service to God. At worst, it meant she was pledged as a human sacrifice.In deep grief, Jephthah has said he cannot go back on his vow (Judges 11:35). His daughter doesn't protest or resist—instead, she agrees. She says plainly that because the Lord did as Jephthah asked, he must now follow through and do to her whatever he promised (Numbers 30:1–2). This is the way of vows to the Lord, and she understands it.
This unnamed daughter expresses far more maturity than her father. She does have one request, however, in the following verse (Judges 11:37). The exact nature of her petition suggests a less-drastic interpretation of her father's vow, but her resolute obedience is still impressive.
