This is perplexing. Sure, the Bible tells us that disobedient sons must be stoned to death (
Deuteronomy 21:18-21), but that doesn't technically apply to daughters. So, in this case, we must fall back on the admonition of Proverbs 20:30:
The blueness of a wound cleanseth away evil: so do stripes the inward parts of the belly.
I think you know what you have to do. And, for God's sake, keep at it until she relents.
