Ze’eiri says: Permitted and forbidden substances combine with regard to the prohibition against offering leaven on the altar, as well, as it states: “For any [kol] leaven and any [kol] honey shall not be offered as a burnt-offering before the Lord” (Leviticus 2:11). This indicates that one is also liable for sacrificing leaven in a mixture in addition to the liability for sacrificing pure leaven. The Gemara asks: In accordance with whose opinion did Ze’eiri issue his ruling? It is in accordance with the opinion of Rabbi Eliezer, who derives from the term kol in the verse “You shall eat nothing [kol] leavened” (Exodus 12:20) that a mixture with part leaven is forbidden on Passover.

The Gemara raises a difficulty: If so, then with regard to the matter of leavened bread on Passover, one should also be liable for eating leaven combined with a permitted substance, e.g., less than an olive-bulk of bread soaked in wine, so that the volume is now an olive-bulk. The Gemara answers: Yes, indeed it is so. Rather, when Ze’eiri specifies that the prohibition applies with regard to sacrificing leaven in offerings, he meant to exclude the statement of Abaye, who says: There is significance to sacrificing less than an olive-bulk of leaven on the altar, i.e., one is flogged for sacrificing an offering of that kind. By noting that one is liable due to the fact that permitted substances combine with forbidden substances, Ze’eiri teaches us that there is no significance to sacrificing less than an olive-bulk, and therefore this is not punishable by lashes.

§ Rav Dimi sat and stated this halakha of Rabbi Yoḥanan that a permitted substance does not combine with a forbidden substance except in the case of a nazirite. Abaye raised an objection to his opinion from a mishna (Tevul Yom 2:3): In a case where the thick soup was made with produce that had the status of teruma but the garlic and oil therein were of non-sacred produce, and one who was ritually impure who immersed that day and is waiting for nightfall for the purification process to be completed touched some of the contents, he has disqualified all the contents of the pot from being eaten, as it all is considered teruma soup. However, if the thick soup was made with produce of non-sacred status but the garlic and the oil had the status of teruma produce, and one who immersed himself that day touched some of them, he has disqualified only the contents in the place that he touched.

Abaye continues: And we discussed this issue: Why are the contents in the place that he touched disqualified? Since the primary ingredients of the dish are of non-sacred produce, it should not be disqualified by contact with one who immersed himself that day. And Rabba bar bar Ḥana says that Rabbi Yoḥanan says: What is the reason that the contents become disqualified? It is due to the fact that a non-priest is flogged for eating an olive-bulk of the soup, as anything into which teruma is mixed is considered teruma by Torah law.

Abaye concludes his question: What is Rabbi Yoḥanan’s reason that one is flogged for eating this mixture?
