What is the default assumption regarding a gentile's intent when an animal is slaughtered? The rabbis hold that we do not automatically assume a gentile intends it for idol worship unless he explicitly says so, while Rabbi Eliezer holds a gentile's default intent is for idol worship. Rabbi Yosi argues that even if he does intend it for idol worship, we do not say that one person's intent affects another person's act of slaughter. The Gemara presents two ways to explain this dispute and whether the principle of one person intending and another performing the action applies outside the Temple just as it does inside.

What is the status of an animal if the slaughter was performed with the intent to perform a later part of the service, like throwing the blood or burning the fat, for idol worship? Rabbi Yochanan rules that the animal is disqualified because we can transfer intent from one action to another, and we learn the laws outside the Temple from the laws inside. Reish Lakish rules that it is permitted because we do not transfer intent from one action to another outside the Temple. The Gemara notes they hold the same argument regarding internal Temple sacrifices and l'shma intent, and then explains why it was necessary to state that they argue in both cases. A difficulty is raised against Rabbi Yochanan and Reish Lakish from Rabbi Yosi's position in the Mishna, but is resolved. A braita is then brought to support Rabbi Yochanan's position.

What is the law if someone performs shechita and only thinks about sprinkling the blood for idol worship after the slaughter is finished? The Gemara cites a case in Caesarea where the Sages did not rule whether it was forbidden or permitted. The issue is whether or not a later action or statement retroactively proves the initial intent. After attempting to connect their ruling with the rabbis' and Rabbi Eliezer's positions, that suggestion is rejected and they say it connects with Rabban Shimon ben Gamliel's ruling. However, the Gemara tries to figure out which ruling of Rabban Shimon ben Gamliel it connects to.

Rav Yehuda says in the name of Shmuel that the halakha follows Rabbi Yosi, meaning the gentile's intent does not disqualify the Jew's shechita. The Gemara brings a story where gentiles gave animals to a Jewish butcher and stated the blood and fat were for them, and it was permitted.

Rav Ashi qualifies that if a gentile gives money to a Jewish butcher under Rabbi Eliezer's view, it is only forbidden if the gentile is powerful enough that the butcher cannot refuse his intent.
