Talmud for Terumot 1:5
אֵין תּוֹרְמִין מִן הַלֶּקֶט, וּמִן הַשִּׁכְחָה, וּמִן הַפֵּאָה, וּמִן הַהֶפְקֵר, וְלֹא מִמַּעֲשֵׂר רִאשׁוֹן שֶׁנִּטְּלָה תְּרוּמָתוֹ, וְלֹא מִמַּעֲשֵׂר שֵׁנִי וְהֶקְדֵּשׁ שֶׁנִּפְדּוּ, וְלֹא מִן הַחַיָּב עַל הַפָּטוּר, וְלֹא מִן הַפָּטוּר עַל הַחַיָּב, וְלֹא מִן הַתָּלוּשׁ עַל הַמְחֻבָּר, וְלֹא מִן הַמְחֻבָּר עַל הַתָּלוּשׁ, וְלֹא מִן הֶחָדָשׁ עַל הַיָּשָׁן, וְלֹא מִן הַיָּשָׁן עַל הֶחָדָשׁ, וְלֹא מִפֵּרוֹת הָאָרֶץ עַל פֵּרוֹת חוּצָה לָאָרֶץ, וְלֹא מִפֵּרוֹת חוּצָה לָאָרֶץ עַל פֵּרוֹת הָאָרֶץ. וְאִם תָּרְמוּ, אֵין תְּרוּמָתָן תְּרוּמָה:
One may not set aside <i>Terumah</i> from the <i>Leket</i> [fallen gleanings given to the poor], or from the <i>Shikhecha</i> [forgotten sheaves given to the poor], or from the <i>Pe'ah</i> [corner of the field that must be given to the poor], or from the <i>Hefker</i> [ownerless], and not from the first tithe whose <i>Terumah</i> has already been taken, or from <i>Ma'aser Sheni</i> [second tithe, which must be eaten in Jerusalem] or <i>Hekdesh</i> [consecrated donation] that has been redeemed, and not from that which is obligated [in <i>Terumah</i>] for that which is not obligated, and not from that which is not obligated to that which is obligated, and not from the picked to the unpicked, and not from the unpicked to the picked, and not from the <i>Chadash</i> [grain from the current year that one is forbidden to eat] for the <i>Yashan</i> [grain from the previous year that one is permitted to eat], and not from the <i>Yashan</i> for the <i>Chadash</i>, and not from the fruits of the Land [of Israel] for fruits from outside the Land, and not from fruits outside the Land for fruits of the Land. And if one did set aside <i>Terumah</i> [from these types of produce], one's <i>Terumah</i> is not [valid] <i>Terumah</i>.

If a qab of new grain and one of old bit one another38While two doughts together are obligated for ḥallah as noted in the previous Halakhah, it is forbidden to give heave from one year’s harvest for another year’s (Mishnah Terumot 1:5). Everybody agrees that ḥallah must be given from both kinds of grain; the question is only how this has to be done., Rebbi Ismael says one should take from the middle but the Sages prohibit this. If somebody takes ḥallah from a single qab, Rebbi Aqiba declares it to be ḥallah but the Sages say, it is not ḥallah.
If ḥallah of two qabim was taken separately, when he then combinrd them together into one dough, Rebbi Aqiba exempts but the Sages obligate; it turns out that the severity39Of R. Aqiba who treats ḥallah from less than the minimal volume as genuine ḥallah. becomes a leniency.
