Reference for Challah 4:8
רַבָּן גַּמְלִיאֵל אוֹמֵר, שָׁלֹשׁ אֲרָצוֹת לַחַלָּה. מֵאֶרֶץ יִשְׂרָאֵל וְעַד כְּזִיב, חַלָּה אֶחָת. מִכְּזִיב וְעַד הַנָּהָר וְעַד אֲמָנָה, שְׁתֵּי חַלּוֹת, אַחַת לָאוּר וְאַחַת לַכֹּהֵן. שֶׁל אוּר יֶשׁ לָהּ שִׁעוּר, וְשֶׁל כֹּהֵן אֵין לָהּ שִׁעוּר. מִן הַנָּהָר וְעַד אֲמָנָה וְלִפְנִים, שְׁתֵּי חַלּוֹת, אַחַת לָאוּר וְאַחַת לַכֹּהֵן. שֶׁל אוּר אֵין לָהּ שִׁעוּר, וְשֶׁל כֹּהֵן יֶשׁ לָהּ שִׁעוּר. וּטְבוּל יוֹם אוֹכְלָהּ. רַבִּי יוֹסֵי אוֹמֵר, אֵינוֹ צָרִיךְ טְבִילָה. וַאֲסוּרָה לַזָּבִים וְלַזָּבוֹת לַנִּדָּה וְלַיּוֹלְדוֹת, וְנֶאֱכֶלֶת עִם הַזָּר עַל הַשֻּׁלְחָן, וְנִתֶּנֶת לְכָל כֹּהֵן:
Rabban Gamliel says, There are three regions with regard to [the laws of] <i>Challah</i>: From the land of Israel to Keziv, one [portion of] <i>Challah</i>; from Keziv to the river and to Amanah, two [portions of <i>Challah<i> - one to the fire and one to the priest, with [the one] to the fire having a minimum measure, and [the one] to the priest lacking a minimum measure; from the river and from Amanah and inward, two [portions of] <i>Challah</i>, one for the fire and one for the priest, with [the one] for the fire lacking a minimum measure, and [the one] for the priest having a minimum measure. And [a impure priest] who has immersed himself, but it is still day, may eat it. Rabbi Yosei says, he does not require immersion. But it is forbidden to <i>Zavim</i> [sing., <i>Zav</i>, males who have certain atypical genital discharges, which render them impure] and </i>Zavot<i> [sing., <i>Zavah</i>, females who have certain types of atypical genital discharges, distinct from their menses, which render them impure], to the <i>Niddah</i> [a female who has menstrual discharges which render her impure], and to women after childbirth. Though it may be eaten with a non-<i>Kohen</i> at the [same] table and it may be given to any <i>Kohen</i>. </i></i>
