וְאֵ֣ת אֲשֶׁר֩ חָטָ֨א מִן־הַקֹּ֜דֶשׁ יְשַׁלֵּ֗ם וְאֶת־חֲמִֽישִׁתוֹ֙ יוֹסֵ֣ף עָלָ֔יו וְנָתַ֥ן אֹת֖וֹ לַכֹּהֵ֑ן וְהַכֹּהֵ֗ן יְכַפֵּ֥ר עָלָ֛יו בְּאֵ֥יל הָאָשָׁ֖ם וְנִסְלַ֥ח לֽוֹ׃ (פ)
И он возместит за то, что он сделал неправильно в святом, и добавит пятую часть к нему, и дать это священнику; и священник очистит его от овна жертвы вины, и он будет прощен.
Mishnah Meilah
Five things in an olah combine with one another: the flesh, the fat, the fine flour, the wine and the oil. And six in a todah: the flesh, the fat, the fine flour, the wine, the oil and the bread. Terumah, terumah of the tithe, terumah of the tithe separated from demai, hallah and first-fruits combine with one another to make up the size required to render other things forbidden and to be liable for the payment of a fifth.
Mishnah Keritot
Rabbi Akiva declares one liable to an asham talui for sacrilege; But the sages declare him exempt. Rabbi Akiba admits that he does not bring his restitution money until he becomes aware [of his trespass], when he must bring with it a certain asham. Rabbi Tarfon: Why should he bring two ashams? Rather, let him set aside the principal with an added fifth, and bring an asham the value of two sela's and stipulate: “If I did commit sacrilege, here is my restitution and this my asham; and if the sacrilege was doubtful, let the money be a freewill gift and the [offering an] asham talui;” since the same type of sacrifice he brings for a case where he doesn’t know, he brings for one where he does know.
