Jesus, do you guys read much?
Was Samuel sacrificed as a death offering according to Hannah's vow?
Well, let's see. Book says Jeptha makes a promise to take the first thing that comes out the door and make it "belong to Yahweh, and I shall sacrifice it as a burnt offering."
Compare this with Hannah's vow that she would give a boy "to Yahweh for the whole of his life and no razor shall ever touch his head."
A careful reader will note the distinction.
As mentioned earlier, the mention of his daughter's virginity is likely pointless unless the idea that she would live as a virgin perpetually is being conveyed. The idea doesn't seem to be 'I'm going to die, but I have never had sex and never will'. The two just don't jibe.
Hmm. No. This was not mourning because she was never going to get laid, this was mourning because she would die childless. That was a pretty big deal 1,000 years BC in the region. Nobody gave a damn whether a chick was sexually fulfilled or not. What doesn't jibe is applying 21st century attitudes to 11th century BC realities.
It's extremely unlikely that any attempt to offer a human as an actual burnt sacrifice would have been tolerated in Israel at this time. It's highly doubtful that Jepthah could have pulled it off.
Who, precisely, was going to stop the warlord who just kicked the hell out of the Amorites from doing anything? Part of the deal he struck with the elders of Gilead was that, if he was successful, he would be the chief. Again, it is important to look at the historical context when thinking about these stories.
