Jephthah's daughter

In the last killing, the spirit of the Lord came upon Jephthah and he promised that he would offer to God a burned sacrifice of whatever came out to greet him if God would help him massacre the Ammonites. God came through with his end of the deal by delivering 20 cities into Jephthah's hand and "he smote them ... with a very great slaughter."

When Jephthah returned home after slaughtering the Ammonites, his daughter came out to meet him.

Jephthah came to Mizpeh unto his house, and, behold, his daughter came out to meet him with timbrels and with dances. Judges 11:34

When Jephthah saw his daughter, he tore his clothes and told her that he had opened his mouth to God.

When he saw her ... he rent his clothes, and said, Alas, my daughter ... for I have opened my mouth unto the LORD, and I cannot go back. 11:35

His daughter (who is unnamed in the Bible) said Jephthah should do whatever the hell he said he'd do when he opened his big mouth to the Lord.

My father, if thou hast opened thy mouth unto the LORD, do to me according to that which hath proceeded out of thy mouth. 11:36

What had proceeded out of Jephthah's mouth was, of course, a God-inspired promise to God to kill whatever greeted him. And so, by God, that's what he did. A man's got to do what a man's got to do.

And ... her father ... did with her according to his vow which he had vowed. 11:39

God inspired Jephthah to make the vow, so he expected him to abide by it. And God was so pleased when Jephthah killed his daughter for him that he decided to kill his own son for you.

But I'll save that story for later.
