During the inauguration of the Tabernacle, Aaron and his sons receive specific instructions on how to handle the remains of the dedication sacrifices. Once the permitted time for eating has passed, any remaining meat or bread must be destroyed by fire.
The instructions address the exact nature of these leftovers. The primary approach among commentators is that the command simply refers to whatever remains from the meat and the bread [רמב״ן, הטור הארוך, חזקוני]. However, others suggest that the phrasing indicates a whole piece of meat still sitting before them, rather than mere scraps left on the table after a meal [ספר הברית, מנדלסון המובאים בפרדס יוסף ורד״צ הופמן]. Another perspective expands this requirement, teaching that even ordinary, non-sacred food eaten alongside the sacrifice must be burned if it absorbed the flavor of the holy meat and bread [העמק דבר].
Standard laws regarding sacrificial leftovers typically include a strict warning not to leave anything until morning. Here, that specific warning is absent. Many commentators explain this brevity by noting that the rule was already stated in an earlier command, or that the priests were already well aware that their time to eat was strictly limited to one day and one night [רמב״ן, אבן עזרא, הטור הארוך]. Conversely, others point to practical reasons for this omission. The sheer volume of the ram meat and bread was simply too large for Aaron and his sons to consume in a single day and night. Because leftovers were inevitable, they were not warned against leaving food over, but were merely instructed on how to dispose of it on the second day [ביאור יש״ר, רד״צ הופמן].
A different legal approach suggests that the meat was never actually left until the morning at all. Throughout the days of the inauguration, Moses would completely assemble and disassemble the Tabernacle each day. The daily dismantling meant that the holy space was temporarily removed, causing the sacrifices to be legally disqualified for having left their sacred boundaries. Therefore, the remaining meat was invalidated and burned immediately when the Tabernacle was taken down, making the concept of waiting until morning entirely irrelevant [אמבוהא דספרי המובא בפרדס יוסף].
Finally, the instruction to burn the remains is given as a direct command to the priests, rather than a general, passive rule for the future. This personal phrasing reflects that the instruction was meant specifically for the men standing there at that exact moment. It applied directly to the actual meat resting before them during those unique days of dedication, distinguishing it from permanent laws established for all future generations [ספר הברית המובא בפרדס יוסף].
