(Mishnah): [If one told his wife 'Konam is] what you make until Pesach and I eat', or 'what you make until Pesach and I wear', if she made before Pesach, he is forbidden to eat or wear it after Pesach;

(Gemara): Our Mishnah should say 'what you make until Pesach, I will not [eat or] wear it.'

(Mishnah): '[Konam is what] you benefit from me until Pesach if you go to your father's house before Sukos' and she went before Pesach, she may not benefit from him until Pesach;

[If she benefited before Pesach, and went] after Pesach (but before Sukos, she) transgresses "Lo Yachel Devaro."

(Gemara): She is forbidden to benefit from him already, lest she go after Pesach, and it turns out the Hana'ah from him [was forbidden] retroactively.
