לֹא־אָכַ֨לְתִּי בְאֹנִ֜י מִמֶּ֗נּוּ וְלֹא־בִעַ֤רְתִּי מִמֶּ֙נּוּ֙ בְּטָמֵ֔א וְלֹא־נָתַ֥תִּי מִמֶּ֖נּוּ לְמֵ֑ת שָׁמַ֗עְתִּי בְּקוֹל֙ יְהוָ֣ה אֱלֹהָ֔י עָשִׂ֕יתִי כְּכֹ֖ל אֲשֶׁ֥ר צִוִּיתָֽנִי׃
我居喪的時候沒有吃這聖物，也沒有在不潔淨中動用它，也沒有把它用在死人身上；我聽從了永恆者我的上帝的聲音，照著祢所吩咐我的一切去做了。

ואסורין לעונן – Regarding the [Second] tithe, it is written (Deuteronomy 26:14): “I have not eaten of iot while in mourning,” and regarding First Fruits, it is states (Deuteronomy 26:11): “And you shall rejoice, [together with the Levite and the stranger in your midst]…” which teaches that these are forbidden to someone in mourning (literally, someone whose dead lies before them, as yet unburied).

ומעשר שני שלא נפדה – Second Tithe that became defiled and even if he is in Jerusalem, it is prohibited to eat it until it is redeemed, but a person who eats it in Jerusalem while it is not yet redeemed, is flogged. And its explicit prohibition is from (Deuteronomy 26:14): “I have not cleared out any of it while impure,” whether I am defiled and it is ritually pure, whether I am ritually pure and it is ritually impure. And from where do we learn that Second Tithe which was defiled – that we redeem it in Jerusalem? As it states (Deuteronomy 14:24): “…should you be unable to transport them,” is explained as you are unable to eat it, as it is written (Genesis 43:34): “Portions were served them from the table…”
Rashi
for their bread is for themselves It is fit for them for food, but not to come into the house of the Lord. Another explanation is: אוֹנִים, like bread of mourners, which is contaminated, and the end of the verse proves it: all those who partake thereof become contaminated.
