Why does the Torah use the expression "Bein Ish le'Ishto"?
Ramban (citing Nedarim, 79b) and R. Bachye: It teaches us that, in addition to Nedarim that cause his wife suffering, 1 a husband 2 may also annul Nedarim that adversly affect their marital relationship. 3 4
Ramban: The Sifri and Yerushalmi say that the same applies to a father annulling his daughter's vows. Refer to 30:17:151:1.
Ramban: Such as a Neder not to wear make-up or to withhold intimacy from him.
R. Bachye maintains that this is actually a Kal va?Chomer from Nidrei Inuy Nefesh, since she is Meshubad (obligated) to her husband.
What are the ramifications of the comparison between "Ish le'Ishto" and "Av le'Bito"?
Ramban (in Hilchos Nedarim), R. Bachye (citing the Sifri #1 and Yerushalmi Nedarim, 11:1): It teaches us that a father, like a husband, can only annul Nedarim that are either Inuy Nefesh or Beino le'Veinah. 1
Sifri #2: It compares one to the other regarding all the details that the Pesukim above to teach us that whatever is written by one applies to the other. 2 .
Nedarim, 68a: It teaches us that the father of a Na'arah Me'urasah must annul the Nedarim of his daughter together with the Arus for the Neder to be annuled. 3

Targum Yonasan: It teaches us that even when she is a Na'arah, her father can annul her Nedarim, as long as she is under his jurisdiction, but not once she is married. 1
Kesuvos, 46b: It implies that a father has rights over his daughter as regards the money of her Kidushin, her findings and whatever she produces with her hands, as the Torah writes "bi'Ne'ureha Beis Aviha" - all the benefits of her youth belong to her father'. 2
Kesuvos, 47a: It implies that a Na'arah is under the jurisdiction of her father 3 as regards annuling her Nedarim.

The Sifri and Yerushalmi learn from "Bein Ish le'Ishto Bein Av le'Bito" that, just like a husband annuls only Nedarim of Inuy Nefesh, or Beino le'Veinah (that affect intimacy), also a father. How is 'Beino le'Veinah' applicable to a father?
