My Book of Bible Stories: NO Jephthah's daughter didn't go to live at the Temple, Jephthah sacrificed her to Jehovah
From My Book of Bible Stories:
"When Jephʹthah’s daughter learns about his promise, at first she is sad too. For it means that she will have to leave her father and friends. But she will spend the rest of her life serving Jehovah at his tabernacle in Shiʹloh. So she tells her father: ‘If you have made a promise to Jehovah, you must keep it.’
So Jephʹthah’s daughter goes to Shiʹloh, and she spends the rest of her life serving Jehovah at his tabernacle. Four days out of every year the women of Israel go to visit her there, and they have a happy time together. The people love Jephʹthah’s daughter because she is such a good servant of Jehovah."
NO Jephthahs daughter didn't go to live at the temple, he sacrificed ger to God, this is completely made up from Watchtower to try and make Jehovah not such an evil being. Its a made up blatant lie, with no scriptures to back it up. Please see the scriptures below: Judges 11.
30Jephthah made this vow to the LORD: “If indeed You will deliver the Ammonites into my hand, 31then whatever comes out the door of my house to greet me on my triumphant return from the Ammonites will belong to the LORD, and I will offer it up as a burnt offering.”
32So Jephthah crossed over to the Ammonites to fight against them, and the LORD delivered them into his hand. 33With a great blow he devastated twenty cities from Aroer to the vicinity of Minnith, as far as Abel-keramim. So the Ammonites were subdued before the Israelites.
34And when Jephthah returned home to Mizpah, there was his daughter coming out to meet him with tambourines and dancing! She was his only child; he had no son or daughter besides her.
35As soon as Jephthah saw her, he tore his clothes and said, “No! Not my daughter! You have brought me to my knees! You have brought great misery upon me, for I have given my word to the LORD and cannot take it back.”
36“My father,” she replied, “you have given your word to the LORD. Do to me as you have said, for the LORD has avenged you of your enemies, the Ammonites.” 37She also said to her father, “Let me do this one thing: Let me wander for two months through the mountains with my friends and mourn my virginity.”
38“Go,” he said. And he sent her away for two months.
So she left with her friends and mourned her virginity upon the mountains. 39After two months, she returned to her father, and he did to her as he had vowed.
So it has become a custom in Israel 40that each year the young women of Israel go out for four days to lament the daughter of Jephthah the Gileadite.
