Why does the Torah seemingly repeat the same circumstance regarding a betrothed woman taking a vow twice?
What does one learn with this repetition?
Numbers 30:7-8
But if she is [betrothed] to a man, with her vows upon her or by an utterance of her lips which she has imposed upon herself, and her husband hears it but remains silent on the day he hears it, her vows shall stand, and her prohibition which she has imposed upon herself shall stand.
And Numbers 30:11-12
But if she vowed in her husband's house, or imposed a prohibition upon herself with an oath. and her husband heard and remained silent, and did not hinder her, all her vows shall stand, and every prohibition she imposed upon herself shall stand.
