Reference for Menachot 141:5
אמר רבי יצחק קמה לאו מכלל דלאו בר קמה דלאו בר קמה ולעולם אגם
THE MEN OF JERICHO USED TO REAP [BEFORE THE 'OMER] WITH THE APPROVAL OF THE SAGES, AND USED TO STACK IT WITHOUT THE APPROVAL OF THE SAGES etc. Whom have you heard say that [in certain cases] they [the Sages] forbade them and [in others] they did not forbid them?

These they did with the approval of the Sages: they grafted palms the whole day. they 'rolled up' the Shema', and they reaped before the 'Omer. And these they did without the approval of the Sages: they stacked the corn before the 'Omer, they permitted for use the branches of carob and sycamore trees which had been dedicated to the Temple, and they made breaches in their gardens and orchards so as to allow the poor to [come in and] eat the fallen fruit on Sabbaths and Festivals in years of drought. So R. Meir. Then said R. Judah to him, If they did them with the approval of the Sages then all people could do so! But they did both without the approval of the Sages, save that three they forbade them and three they did not forbid them to do. These they did not forbid them: they grafted palms the whole day. they 'rolled up' the Shema', and they reaped and stacked before the 'Omer. And these they forbade them:<br>
