All chatas-offerings [mentioned] in the Torah precede asham-offerings, except for the asham-offering of the metzora because it is brought to make [the metzora] fit. All asham-offerings [mentioned] in the Torah must be in their second year, and must be [worth at least two] silver shekels; except for the asham- offering of a nazir and the asham-offering of a metzora, which must be in their first year, and need not be [worth two] silver shekels.

Just as they precede [one another] in their offering, so they precede [one another] in their consumption. [Between] a shelamimoffering of yesterday and a shelamim-offering of today, that of yesterday takes precedence. [Between] a shelamim-offering of yesterday and a chatas or asham-offering of today, that of yesterday takes precedence; [these are] the words of R’ Meir. But the Sages say: The chatas-offering takes precedence, because it is [a] most holy offering.
