Yair Aaron asks:
why cant you learn from cul bechor banecha that a daughter does not have to redeem herself?
Yair Aaron, Bk New York
The Kollel replies:
Shalom Rav,
Without going into the Sugya, it seems that your question is asked By Tosfos DH 've'Ihi Mina lan'. Tosfos answers that from the Pasuk "kol B'chor Banecha" we would learn that a father is not obligated to redeem his daughter, but that she is obligated to redeem herself.
Be'virchas Kol Tuv,
