אֶתְרוֹג הַגָּזוּל וְהַיָּבֵשׁ, פָּסוּל. שֶׁל אֲשֵׁרָה וְשֶׁל עִיר הַנִּדַּחַת, פָּסוּל. שֶׁל עָרְלָה, פָּסוּל. שֶׁל תְּרוּמָה טְמֵאָה, פָּסוּל. שֶׁל תְּרוּמָה טְהוֹרָה, לֹא יִטֹּל, וְאִם נָטַל, כָּשֵׁר. שֶׁל דְּמַאי, בֵּית שַׁמַּאי פּוֹסְלִין, וּבֵית הִלֵּל מַכְשִׁירִין. שֶׁל מַעֲשֵׂר שֵׁנִי בִּירוּשָׁלַיִם, לֹא יִטֹּל, וְאִם נָטַל, כָּשֵׁר:
A stolen or dried out ethrog is pasul. (An ethrog) from an asheirah or from a city gone astray (after idolatry) is pasul. (An ethrog) of arlah (forbidden fruit of the first three years) is pasul, [it being written (Leviticus 23:40): "And you shall take for yourselves" — it must be fit for you.] (An ethrog) of unclean terumah is pasul. Of clean terumah — he should not take it; but if he does, it is kasher. Of demai (suspect of not having been tithed) — Beth Shammai rule it pasul, and Beth Hillel rule it kasher, [it being fit for the poor, as it was taught: "The poor may be fed demai."] Of ma'aser sheni, in Jerusalem, he should not take it; but if he took it, it is kasher; [but not outside Jerusalem, for "for yourselves" must be satisfied, i.e., that it be fit for you.]
