11שְׁנַיִם שֶׁבָּאוּ לִמְדִינָה זֶה אוֹמֵר אֲנִי וַחֲבֵרִי כֹּהֵן וְזֶה אוֹמֵר אֲנִי וַחֲבֵרִי כֹּהֵן אַף עַל פִּי שֶׁנִּרְאִין כְּגוֹמְלִין זֶה אֶת זֶה הֲרֵי אֵלּוּ נֶאֱמָנִין וּשְׁנֵיהֶם בְּחֶזְקַת כֹּהֲנִים. וְכֵן עֵד שֶׁאָמַר רָאִיתִי זֶה שֶׁנָּשָׂא כַּפָּיו אוֹ שֶׁאָכַל בִּתְרוּמָה אוֹ שֶׁחָלַק עַל הַגֹּרֶן אוֹ שֶׁקָּרָא בַּתּוֹרָה רִאשׁוֹן וְקָרָא אַחֲרָיו לֵוִי מַחֲזִיקִין אוֹתוֹ בִּכְהֻנָּה עַל פִּיו. וְכֵן אִם הֵעִיד שֶׁזֶּה קָרָא שֵׁנִי בַּתּוֹרָה אַחַר כֹּהֵן מַחֲזִיקִין אוֹתוֹ בִּלְוִיָּה:
When two people come to a particular city, one says: "I and my colleague are priests," and the other says, "I and my colleague are priests," their word is accepted and they are both considered as priests even though it appears that they are in collusion. Similarly, if one witness says: "I saw this person recite the Priestly Blessing," "...eat terumah, "...received terumah in the granary," or "...read first from the Torah and a Levi read after him," he is considered a priest on the basis of this statement. Similarly, if one testified that a person read second from the Torah after a priest, he is considered as a Levite.
