EXOD312 Before Hashem gave the Torah to Bnei Yisrael, he told Moshe: כֹּ֤ה תֹאמַר֙ לְבֵ֣ית יַעֲקֹ֔ב וְתַגֵּ֖יד לִבְנֵ֥י יִשְׂרָאֵֽל׃… וִהְיִ֨יתֶם לִ֤י סְגֻלָּה֙ מִכָּל־הָ֣עַמִּ֔ים “So shall you say to the House of Yaakov [referring to the women] and speak to Bnei Yisrael [referring to the men] … and you will be cherished unto me more than all of the nations” (Shemos 19:3,5). The Toras Chaim (Bava Basra 130a) explains that Hashem deliberately instructed Moshe to speak separately to the women and the men, in order to teach us that the reward of one's mitzvos is shared equally by husband and wife, for the two are in essence one entity.
