Zevachim 10:5-6

Zevachim 10:5

All the sin offerings of the Torah come before guilt offerings except for the guilt offering of a metzora (colloquially a “leper,” but not really) because it is brought to render him fit. All the guilt offerings of the Torah must be two years old and worth two shekels except the guilt offering of a nazir and that of a metzora, which must be one year old and need not be worth two shekels.

Zevachim 10:6

Just as the sacrifices we have discussed take precedence in being offered, they take precedence in being eaten. Between a peace offering from yesterday and one from today, yesterday’s takes precedence. (A peace offering can only be eaten for two days and one night.) Between a peace offering from yesterday and a sin offering or a guilt offering from today (which can only be eaten one day and one night), Rabbi Meir says that yesterday’s peace offering takes precedence (because it expires sooner – the other can still be eaten at night). The Sages, however, say that the sin offering takes precedence because it is a sacrifice of the highest sanctity.
