Pesachim4: 8
שִׁשָּׁה דְבָרִים עָשׂוּ אַנְשֵׁי יְרִיחוֹ, עַל שְׁלֹשָׁה מִחוּ בְיָדָם, וְעַל שְׁלֹשָׁה לֹא מִחוּ בְיָדָם. וְאֵלּוּ הֵן שֶׁלֹּא מִחוּ בְיָדָם: מַרְכִּיבִין דְּקָלִים כָּל הַיּוֹם, וְכוֹרְכִין אֶת שְׁמַע, וְקוֹצְרִין וְגוֹדְשִׁין לִפְנֵי הָעֹמֶר — וְלֹא מִחוּ בְיָדָם.  וְאֵלּוּ שֶׁמִּחוּ בְיָדָם: מַתִּירִין גַּמְזִיּוֹת שֶׁל הֶקְדֵּשׁ, וְאוֹכְלִין מִתַּחַת הַנְּשָׁרִים בַּשַּׁבָּת, וְנוֹתְנִין פֵּאָה לַיָּרָק — וּמִחוּ בְיָדָם חֲכָמִים.
The citizens of Jericho did six things. For three they have reproved them and for three they have not reproved them. And these are the things for which they have not reproved them: They graft palms all day [on the fourteenth of Nissan]; they “wrap” the Shema; and they reap and stack prior to the Omer, but they have not reproved them.  And these are the things for which they have reproved them. They permit the branches which were sacred property [for personal use]; they eat the fallen fruit from beneath [the tree] on the Sabbath; and they give peah from vegetables, and the Sages have reproved them.
