They said to him [Rabban Gamliel]: What about property that fell to her before she was married and she was [subsequently] married [what rights does the husband have to her property]? He said to them: Even this she shouldn't sell, but if she sold it and gave it, it remains [valid]. They said to him: His betrothed is [called] "his wife" and his bride is [called] "his wife"—just as this one's [his bride's] sale [of her property] is void [without his permission], so to this one's [his betrothed's] sale is void. He said to them: With new property [that which came to her since she was married to him] we are ashamed [that he has control over it], but you would roll over us old property [that which came to her before she was married to him]!? But our rabbis returned and voted about property that fell to her before she was married and [then] was married, that if she sold it and gave it, it is void [without the husband's permission]. Rabbi Shimon distinguishes between two [kinds of] property: Property that is known to the husband, she shouldn't sell it, and if she sold it and gave it, [the sale] is void, for it is with this understanding that she was married; but property that is not known to the husband, she shouldn't sell it (Ehrfurt manuscript omits לא), and if she sold it and gave it, it stands.
