Talking Talmud

What offerings were made in the wilderness, after leaving Egypt? In Gilgal? What verses spurred Rabbi Shimon's opinion to say only some few sacrifices were made at Gilgal? The Pesach offering was made, of course. Note that the Children of Israel left Egypt without having been circumcised for years and years - until they then did circumcise themselves, with implications for their religious lives, including their offerings. Also, the 3 places the Divine Presence rested on the land of Israel: Shilo, Nov & Givon, and the Temple in Jerusalem. Plus, the fact that all of these places seem to have been in Binyamin's portion of the land of Israel. But what about Yehudah? And even Yosef? Also, the chronology of where the Mishkan was when, from the verses themselves.

When the Children of Israel stopped for some time at Gilgal, when private offerings were allowed. But what offerings did they actually bring? And which were simply not done then? Also, a deep dive into the sacrifices brought by a nazir. Plus, what it takes for an offering to be voluntary.

Which animals were allowed to be sacrificed altogether? Male, female, blemishes and not, etc. But what about a treyfa (an animal that was going to die within the year)? Plus, the Gemara probes the implications from this status to the animals that boarded Noah's ark. Distinguishing between "clean" and "unclean" animals may have been unclear before the giving of the Torah, but they could derive which animals were kosher and not by virtue of how many of each was saved on the ark (7 for the kosher animals, even if they didn't yet know that they would be "kosher" animals). Also, the Gemara eases into halakhot about non-Jews bringing offerings outside of the Temple, and on private altars that were not acceptable for the Jews (at that time). Plus, the possibility of lacunae in the biblical verses cited by the Gemara. And the Jews could advise the non-Jews as to how to make the offerings, but not do it themselves.

A dispute over whether one is liable for slaughtering a premature guilt-offering outside of the Temple - a very specific case. Also, if what you slaughter isn't fit to be a Temple offering to begin with, for example, than there's no liability. Plus, offerings that were allowed to be brought outside of the courtyard (or, rather, the Tabernacle) because it hadn't yet been established as the sole location for this. Thus, in the wilderness - offerings were made in the Tent of the Meeting, and largely by the class of the first born, rather than the kohanim. At least, until the kohanim were established at the day of establishing the Tabernacle itself. Also, the deaths of Nadav and Avihu, their father's reaction, their uncle's reaction, and what it means to sanctify God in their deaths.

On blemished animals, premature animals, an animal and its offspring - any of these offered outside of the Temple would not make the person offering them liable, but they still violate a negative commandment. With some dispute over premature animals. Plus, the people who aren't ready to bring their offering - not the animal being unready, but the person who needs to bring it have no yet finished the time they need to wait to fulfill the process of becoming ready for the offering. For example, waiting the number of days before the possibility of purification kicks in, as per the Torah. Plus, the Amoraic refining the phrasing of the mishnah.
