The other point I would make is that the Hebrew Scriptures do not white wash these stories all the warts are left in there so that we don’t sanitize them and turn these people into saints in this way we realize they were human beings with all their frailties and shortcomings and that is the real lesson we should learn and try not to make the same errors they did as well.....
I would agree, the overall tone of the Book of Judges is to show that under the Judges, (really, not Judges but a collection of warriors and heroes), the Hebrews became lawless and chaotic and accepted a lot of bad behavior. The purpose of the book was to show why Israel needed a King.
Yet in the New Testament Letter to the Hebrews, you have this passage.
And what more shall I say? I do not have time to tell about Gideon, Barak, Samson and Jephthah, about David and Samuel and the prophets,
In short, Jephy is put up there with the Hall of Fame of Bible Greats, despite the fact he was a son of a Harlot who engaged in human sacrifice and slaughtered 42,000 of his own people for dissing him.
Again, the issues here is not to really discuss Jephy, it's to discuss God.
God knew what was going to happen when Jephy made his vow. He gave Jephy a victory over the Ammonites anyway, and he slaughtered a lot of them, including women and children. Then he allowed Jephy's daughter to come out of the house first before a goat or a chicken.
On that note, did anyone think that God was going to be impressed with a goat or a chicken for a sacrifice? "Wow, 30 Cities defeated, and you gave me a chicken!"
More to the point, Jephy and his daughter are absolutely TERRIFIED of what might happen if they don't go through with it. And they should be, given that this is a God who drowns babies and demands his followers slaughter each other over such petty crimes as having the wrong kind of sex and picking up sticks on the Sabbath.
To them, the Human Sacrifice was the LEAST BAD OPTION under the circumstances.
