Talmud su Menahot 7:5
הָאוֹמֵר הֲרֵי עָלַי תּוֹדָה, יָבִיא הִיא וְלַחְמָהּ מִן הַחֻלִּין. תּוֹדָה מִן הַחֻלִּין וְלַחְמָהּ מִן הַמַּעֲשֵׂר, יָבִיא הִיא וְלַחְמָהּ מִן הַחֻלִּין. תּוֹדָה מִן הַמַּעֲשֵׂר וְלַחְמָהּ מִן הַחֻלִּין, יָבִיא. הַתּוֹדָה הִיא וְלַחְמָהּ מִן הַמַּעֲשֵׂר, יָבִיא. וְלֹא יָבִיא מֵחִטֵּי מַעֲשֵׂר שֵׁנִי, אֶלָּא מִמְּעוֹת מַעֲשֵׂר שֵׁנִי:
Chi dice "Accetto su me stesso [per portare] un sacrificio di ringraziamento" deve portare lui e il suo pane da soldi non sacri. [Se dice "Accetto a me stesso di portare] un sacrificio di ringraziamento con denaro non sacro e il pane di ma'aser [ sheni ]" [la seconda decima del prodotto, che deve essere portato a Gerusalemme e consumato lì], deve portarlo e il suo pane da soldi non sacri. [Se dice "Accetto a me stesso di portare] un sacrificio di ringraziamento da ma'aser [ sheni ] e il pane da denaro non sacro", potrebbe portarlo. [Se dice "Accetto a me stesso di portare] sia il pane che il sacrificio da ma'aser [ sheni ], potrebbe portarlo. Ma non può portare [la sua offerta] dal grano di ma'aser sheni , piuttosto dai soldi di Ma'aser Sheni .
Jerusalem Talmud Maaser Sheni
The Babli (Menaḥot 81b–82a) gives as a reason for the breads that the verse requires the sacrifice to be brought with its breads, i. e., from the same source. Since Second Tithe itself consists of produce, it is clear that the animal itself must be bought with tithe money. Therefore, the bread also should come from tithe money. (R. Jeremiah disagrees with the Mishnah.)
The Yerushalmi disagrees and holds that tithe money is holy and the holiness of a dedicated sacrifice can fall on the wheat only if the latter is profane. This proves R. Zeïra’s point.” What is the difference between wheat and money? It must be that when it was bought, the holiness of tithe left it. Rebbi Ḥinena asked before Rebbi Mana: Why should he not bring wheat, the heave132This is not the usual heave but one bread from each kind brought with the thanksgiving sacrifice; it is called heave in Lev. 7:14. to the Cohen and the rest for the owners, why does he not bring133He disagrees with R. Yose whose argument is tenable only if he holds with R. Meїr that tithe money is Heaven’s property. But since the previous paragraph presupposes that we hold with R. Jehudah that Second Tithe and tithe money are property of the farmer, there is no reason why Second Tithe wheat should not be used since all the breads will be eaten in holiness, either by the farmer’s family or by the Cohen.? He said to him, think of it, if the blood is spilled134On the way to the altar. The entire sacrifice is invalidated if its blood is not sprinkled on the altar. does the bread not become unusable135If anything happens to the sacrifice, the bread is wasted and has to be burned. But if the breads are bought, they will be replaced by other bought breads.?
