So was it a human sacrifice, or a devotion to the Lord, like the WT maintains?
Looks like Jewish scholars are not in agreement on this. They do agree however that Jephthah was a self-righteous idiot...Perfect Watchtower leadership material.
- "Firstly it is important to emphasize that Judaism has always viewed human sacrifices as a reprehensible abomination. Regarding the Canaanites, Moses says: “For every abomination to G‑d which He hates, they did to their gods; for also their sons and their daughters they would sacrifice in fire to their gods.”3
Based on this idea, many of the biblical commentators maintain that Jephthah did not offer his daughter as a sacrifice. In fact, his original vow, “whatever comes forth . . . shall be to G‑d, and I will offer it up for a burnt-offering,” had a dual intention: if it will be a person, then it “shall be [consecrated] to G‑d”; and if it should be an animal, then “I will offer it up as a burnt offering.” (The Hebrew prefix ו which precedes the words “I will offer it” can be translated as “and” or “or.”)
According to this interpretation, Jephthah’s daughter was sent to the mountains to live in seclusion. She never married and dedicated her life to the service of G‑d.
Other biblical commentators5 disagree. Though Jephthah was one of the Israelite judges, he was chosen for the position because of his bravery and might, not because of his Torah scholarship—indeed, he was woefully ignorant.6 And though he was not bound whatsoever by the vow he made—as it clearly transgressed the rules of the Torah—he ignorantly went ahead and offered his daughter as a sacrifice.
Had he only consulted with Phinehas, the learned high priest of the time, he would have been informed of his error. But that didn’t happen. Jephthah was too arrogant to travel to Phinehas to receive guidance: “I am the general of the Israelite forces, and I should go to him?!” And Phinehas was too proud to unilaterally go to Jephthah to advise him: “He needs me; why should I make the trip?”
The hubris demonstrated by these two leaders cost an innocent girl her life. According to the Midrash7 both were punished. Phinehas lost the divine spirit that had hitherto rested upon him. Jephthah became ill, and he lost many of his limbs. Because his limbs were buried in many locations, the Bible says that Jephthah was “buried in the cities of Gilead.”8 "

Apparently Jephthah went to pieces after this..... literally.
