הַמַּקְדִּישׁ מַעֲשֵׂה יְדֵי אִשְׁתּוֹ, הֲרֵי זוֹ עוֹשָׂה וְאוֹכֶלֶת. הַמּוֹתָר, רַבִּי מֵאִיר אוֹמֵר, הֶקְדֵּשׁ. רַבִּי יוֹחָנָן הַסַּנְדְּלָר אוֹמֵר, חֻלִּין:
If one consecrates (to the Temple) the handiwork of his wife, she works and eats, [for they instituted that he feed her in exchange for her handiwork, for which reason, according to all, she works and eats.] [If he consecrated] the surplus [of her handiwork, what she makes above and beyond what she needs for her food, and not the handiwork itself], R. Meir says: It is consecrated, [for he holds that one can consecrate something that has "not yet come to the world."] R. Yochanan Hasandler says: It is chullin (non-consecrated). [The halachah is not in accordance with R. Meir, but with R. Yochanan Hasandler, who says that it is chullin, for one cannot consecrate something that has "not yet come to the world."]
