The Mishna compares the details regarding the laws of semicha (leaning) and tenufa (waving). Semicha has a stringency in that all owners of the sacrifice are obligated to perform it, while the same does not hold true for tenufa. However, waving applies to both individual and communal sacrifices, to animals that are both alive and slaughtered, and to both animals and non-living items, such as breads. These do not apply to semicha, which is only performed on live animals and primarily for individual sacrifices.

The Gemara brings a scriptural source for the ruling that semicha is obligatory for all owners of the sacrifice, while only one person performs tenufa on behalf of the others. A difficulty is raised against the fact that semicha is limited only to live animals based on a Mishna in Tamid 33b, which describes a process of semicha performed by a Kohen Gadol on a slaughtered animal. However, Abaye explains that this specific semicha is performed merely out of respect for the Kohen Gadol and is not a formal requirement of the sacrificial service.

The loaves of the lechem hapanim (showbread) and the loaves of the shtei halechem (two loaves) were kneaded separately. The shtei halechem were baked separately, while the lechem hapanim - twelve in total - were baked two at a time. The Gemara brings the scriptural source for these details.

What shape were the lechem hapanim? Rabbi Chanina and Rabbi Yochanan each describe a different shape: either like an "open box" or like a "rocking boat." The Gemara analyzes these different opinions based on other known details regarding the various components of the table (shulchan) upon which the bread sat.
