What is this Pasuk coming to teach us about the Nedarim of an Arusah?
1.
Rashi and R. Bachye: It teaches us that if her betrothed endorses her Neder (by not annulling it on the day that he hears it) remains intact (even if her father annuls it - R. Bachye).
2.
Targum Yonasan: It teaches us that if she declared a Neder after she married and her husband, endorses it on the day that he hears it, or is silent with the intention of endorsing it, 1 the Neder stands.
3.
Nedarim, 73a: ?Veshama Iyshah? implies that if the Arus is deaf, he cannot annul his Arusah's Nedarim.
