When Rabbi Zeira heard that Rabbi Yochanan and Rabbi Asi were eating meat slaughtered by a Cuti, he assumed they must have been aware of a prior decree permitting it. He reasoned that had it been forbidden, they would have inadvertently consumed non-kosher meat - a mistake God would not allow to befall the righteous. This principle is derived from the story where God protected the animal of a righteous person from sin; how much more so would He protect the righteous individuals themselves! From this incident, the Gemara concludes that Rabbi Zeira eventually conceded to Rabbi Yaakov that the shechita of a Cuti had been forbidden by the decree of Rabban Gamliel, even if a Jew was present to supervise the process.

The Gemara explains that although Rabban Gamliel and his court originally decreed that the shechita of Cutim was unacceptable, the restriction expanded over time. A story is told of Rabbi Meir, who forbade their wine after discovering that a minority of the Cutim worshipped idols. Later, a subsequent generation of Amoraim in Israel - Rabbi Ami and Rabbi Asi - were informed that the Cutim had ceased to be "Torah worshippers" entirely. Consequently, they accorded them the status of gentiles regarding all halakhic matters. The Gemara clarifies that while their shechita and wine had been forbidden by Rabbi Meir and Rabban Gamliel previously, the ruling was only universally accepted and finalized in the time of Rabbi Ami and Rabbi Asi.

The Gemara presents two other instances where the concept of God protecting the righteous from accidental transgression is applied. The first involves Rabbi Zeira regarding the laws of demai (produce from an am haaretz which tithes may not have been separated). When produce purchased from an am haaretz is mixed with other ingredients, its status is debated. Seeing Rav Asi eating such a mixture without tithing it, Rabbi Zeira inferred that it must be permitted, as God would not allow a righteous person to eat untithed food.

The Gemara challenges this conclusion based on a braita that appears to forbid such mixtures. However, the Gemara resolves this in two possible ways by explaining that the case in the braita involved a unique type of "mixture." While the initial difficulty was raised from the second half of the braita, the Gemara also questions the first part, which permits returning food to a neighbor who is an am haaretz without re-tithing it (as we do not suspect the neighbor of swapping the food). Although three other Tannaitic sources suggest we should fear a swap, the Gemara distinguishes each case as unique.

A third situation is mentioned where Rabbi Zeira applied the principle of divine protection. It concerns Rabbi Yehuda haNasi in the footsteps of Rabbi Meir permitting produce in Beit Shean to be eaten without tithing, on the basis that Beit Shean was not considered to be within the halakhic borders of the Land of Israel.
