Tosefta for Pesachim 111:12
ואלו שלא מיחו בידם מרכיבין דקלים כל היום וכורכין את שמע וקוצרין וגודשין לפני העומר ואלו שמיחו בידם מתירין גמזיות של הקדש של חרוב ושל שקמה ופורצין פרצות בגנותיהן ופרדסיהן להאכיל נשר לעניים בשבתות וימים טובים בשני בצורת נותנין פיאה לירק ומיחו בידם חכמים
And these were with the consent of the Sages: They grafted palm trees all day [of the fourteenth], they 'wrapped up' the shema', and they harvested before the 'omer.<span class="x" onmousemove="('comment',' V. supra p. 277, n. 6.');"><sup>25</sup></span> And these were without the consent of the Sages: They stacked [the corn] before the 'omer,<span class="x" onmousemove="('comment',' As it is quite unnecessary, for the produce will not suffer loss if it is left unstacked until after the 'omer, and while engaged in stacking it, they might come to eat it.');"><sup>26</sup></span> and they made breaches in their gardens and orchards to permit the poor to eat the fallen fruit in famine years on Sabbaths and Festivals, and they permitted [for use] the branches of carob and sycamore trees belonging to hekdesh: this is R'Meir's view. Said R'Judah to him, If they did [these things] with the consent of the Sages, then all people could do so! But they did both without the consent of the Sages, [save that] three they forbade them [to do], and three they did not forbid them [to do].
