הָאוֹמֵר לַחֲבֵרוֹ, צֵא וְקַדֵּשׁ לִי אִשָּׁה פְלוֹנִית וְהָלַךְ וְקִדְּשָׁהּ לְעַצְמוֹ, מְקֻדֶּשֶׁת. וְכֵן הָאוֹמֵר לְאִשָּׁה, הֲרֵי אַתְּ מְקֻדֶּשֶׁת לִי לְאַחַר שְׁלשִׁים יוֹם, וּבָא אַחֵר וְקִדְּשָׁהּ בְּתוֹךְ שְׁלשִׁים יוֹם, מְקֻדֶּשֶׁת לַשֵּׁנִי. בַּת יִשְׂרָאֵל לְכֹהֵן, תֹּאכַל בַּתְּרוּמָה. מֵעַכְשָׁיו וּלְאַחַר שְׁלשִׁים יוֹם, וּבָא אַחֵר וְקִדְּשָׁהּ בְּתוֹךְ שְׁלשִׁים יוֹם, מְקֻדֶּשֶׁת וְאֵינָהּ מְקֻדֶּשֶׁת. בַּת יִשְׂרָאֵל לְכֹהֵן אוֹ בַת כֹּהֵן לְיִשְׂרָאֵל, לֹא תֹאכַל בַּתְּרוּמָה:
If one said to his friend: "Go and betroth that woman to me," and he went and betrothed her to himself, she is betrothed. [The gemara explains: What is the intent of "and he went"? He went with deception. And this explains: "he said to his friend" rather than: "he said to his messenger" — to apprise us that even though he did not appoint him a messenger ab initio for this, but just told him: "Betroth that woman to me," if he betrothed her to himself, he is spoken of as having gone "with deception," and he is considered a deceiver.] Likewise, if one said to a woman: "You are betrothed to me after thirty days," and another came and betrothed her within the thirty days, she is betrothed to the second. [And he can wed her even within those thirty days]. If she were the daughter of a Cohein (betrothed) to an Israelite [If the one who was betrothed after thirty days were the daughter of a Cohein], she may eat terumah [all those thirty days. For she was not rendered unfit to eat of the terumah of her father's house. And if she were the daughter of an Israelite (betrothed) to a Cohein, she may not eat terumah, not yet being the wife of a Cohein.] (If one said to her: "You are betrothed to me) from now after thirty days," and another came and betrothed her within the thirty days, she is betrothed and not betrothed [and she requires a get from both.] If she were the daughter of an Israelite (betrothed) to a Cohein, or the daughter of a Cohein (betrothed) to an Israelite, she may not eat terumah.
