Mishnah 1א׳
אֵין מַקְדִּישִׁין לִפְנֵי הַיּוֹבֵל פָּחוֹת מִשְּׁתֵּי שָׁנִים. וְלֹא גוֹאֲלִין לְאַחַר הַיּוֹבֵל פָּחוֹת מִשָּׁנָה. אֵין מְחַשְּׁבִין חֳדָשִׁים לַהֶקְדֵּשׁ. אֲבָל הַהֶקְדֵּשׁ מְחַשֵּׁב חֳדָשִׁים. הַמַּקְדִּישׁ אֶת שָׂדֵהוּ בִשְׁעַת הַיּוֹבֵל, נוֹתֵן בְּזֶרַע חֹמֶר שְׂעֹרִים חֲמִשִּׁים שֶׁקֶל כָּסֶף. הָיוּ שָׁם נְקָעִים עֲמֻקִּים עֲשָׂרָה טְפָחִים אוֹ סְלָעִים גְּבוֹהִים עֲשָׂרָה טְפָחִים, אֵין נִמְדָּדִים עִמָּהּ. פָּחוֹת מִכָּאן, נִמְדָּדִים עִמָּהּ. הִקְדִּישָׁהּ שְׁתַּיִם אוֹ שָׁלשׁ שָׁנִים לִפְנֵי הַיּוֹבֵל, נוֹתֵן סֶלַע וּפֻנְדְיוֹן לְשָׁנָה. אִם אָמַר הֲרֵינִי נוֹתֵן דְּבַר שָׁנָה בְשָׁנָה, אֵין שׁוֹמְעִין לוֹ, אֶלָּא נוֹתֵן אֶת כֻּלּוֹ כְּאֶחָד:
One may not consecrate [a field of his possession] less than two years before the Jubilee, nor redeem it less than one year after the Jubilee. One does not reckon months to [the disadvantage of] the Sanctuary, but the Sanctuary does reckon months [to its own advantage]. If a man consecrated his field at a time when the law of the Jubilee is in force, he must pay fifty shekels for [every piece of field sufficient for] the sowing of a homer of barley. If the field contained ravines ten handbreadths deep or rocks ten handbreadths high, they are not included as part of the field. But if less than this, they are included. If he consecrated it two or three years before the Jubilee, he must pay one sela [shekel] and one pondion for each year. If he says: “I shall pay for each year as it comes,” they do not listen to him, rather he must pay for all the years together.
Mishnah 2ב׳
אֶחָד הַבְּעָלִים, וְאֶחָד כָּל הָאָדָם. מַה בֵּין הַבְּעָלִים לְבֵין כָּל הָאָדָם, אֶלָּא שֶׁהַבְּעָלִים נוֹתְנִים חֹמֶשׁ, וְכָל אָדָם אֵינוֹ נוֹתֵן חֹמֶשׁ:
It is all the same whether the owner or anyone else [redeems the field]. What is the difference between the owner and any other man? The owner must add one fifth, whereas any other man need not add one fifth.
