Responsa for Sotah 59:3
אמר רב אסי אמר רב ואמרי לה אמר רבה בן איסי אמר רב ר"מ ור' יוסי ור' יהושע ור' אלעזר ור' אליעזר כולהו סבירא להו דאין שני עושה שלישי בחולין
And should you reply [as stated above], 'It can, however, be objected.It applies to a tebul yom because he may be a primary source of defilement', behold he [R. Jose] derived his argument from one lacking atonement and [he] did not raise this objection.<span class="x" onmousemove="('comment',' I.e., that one lacking atonement is different since he may be a primary source of defilement. The reason R. Jose did not raise this objection is evidently because he is no longer regarded as unclean, and the same applies to a tebul yom. Consequently R. Jose cannot be said to agree with Abba Saul, but must agree with the Rabbis, hence the question of R. Johanan. ');"><sup>3</sup></span>

A. Throughout France Hallah is being taken from unleavened cakes by uniting them in a basket. This method is approved by the author of Sefer ha-Terumah, and the author of Eben ha-Ezer. But your method is not to be followed, for while the small pieces are being accumulated they become leaven.
