Ma'aser Sheini5: 4
כֵּיצַד פּוֹדִין נֶטַע רְבָעִי? מֵנִיחַ אֶת הַסַּל עַל פִּי שְׁלֹשָׁה, וְאוֹמֵר: ,,כַּמָּה אָדָם רוֹצֶה לִפְדּוֹת לוֹ בְסֶלַע, עַל מְנָת לְהוֹצִיא יְצִיאוֹת מִבֵּיתוֹ?” וּמֵנִיחַ אֶת הַמָּעוֹת וְאוֹמֵר: ,,כָּל הַנִּלְקַט מִזֶּה מְחֻלָּל עַל הַמָּעוֹת הָאֵלּוּ, בְּכָךְ וְכָךְ סַלִּים בְּסֶלַע”.
How does one redeem reva'i produce? He places the basket before three people, and says: “How much [of this produce] will a person want to buy for himself for a sela, it being under-stood that the expenses come from his pocket?” And he puts down the coins and says: “Whatever was picked from this [crop] is redeemed on these coins, based on the rate of so many baskets per sela.”
Ma'aser Sheini5: 3
כֶּרֶם רְבָעִי, בֵּית שַׁמַּאי אוֹמְרִים: אֵין לוֹ חֹמֶשׁ וְאֵין לוֹ בִעוּר. וּבֵית הִלֵּל אוֹמְרִים: יֵשׁ לוֹ. בֵּית שַׁמַּאי אוֹמְרִים: יֵשׁ לוֹ פֶרֶט וְיֵשׁ לוֹ עוֹלֵלוֹת, וְהָעֲנִיִּים פּוֹדִין לְעַצְמָן. וּבֵית הִלֵּל אוֹמְרִים: כֻּלוֹ לַגַּת.
A fourth-year vineyard, Beis Shammai say: It is not subject to [the law of] a fifth, nor is it subject to [the law of] disposal. But Beis Hillel say: It is subject [to these laws].  Beis Shammai say: It is subject to the law of peret and the law of oleilos, and the poor people redeem for themselves. But Beis Hillel say: All of it [goes] to the wine press.
