[If] a metzora brought his offering when [he was] poor and he became wealthy, or [he brought it] when wealthy and he became poor, everything follows the sin-offering, [these are] the words of R’ Shimon. R’ Yehudah says: [Everything] follows the guilt-offering.

A poor metzora who brought the offering of a wealthy person has fulfilled his obligation. But a wealthy person who brought the offering of a poor person has not fulfilled his obligation. A person may bring the offering of a poor person on behalf of his son, his daughter, his slave or his maidservant, and he [thereby] enables them to eat from offerings. R’ Yehudah says: Just like [a wealthy man must bring for himself the offering of the wealthy] so he must bring for his wife the offering of the wealthy. And the same holds true for any offering in which she is obligated.

[If] the offerings of two metzoraim became mixed up, [and] the offering of one of them was brought and [then] one of [the metzoraim] died. [How does one resolve this predicament?] This is the question that the people of Alexandria asked R’ Yehoshua. He said to them: [The surviving metzora]should sign over his possessions to someone else, and then bring the offering of a poor person.

R’ Eliezer says: [The term] eglah [means] within her first year and [the term] parah [means within her] second [year]. But the Sages say: [The term] eglah [means in her] second [year] while parah [means in her] third or fourth [year]. R’ Meir says: Even [in her] fifth year the elderly [cow] is acceptable, but we do not wait for her, lest she turn black, in order that it not become disqualified.  Said R’ Yehoshua: I did not hear [any term] other than “shelashis.” They said to him: What is this wording “shelashis”? He said to them: This is what I have heard without explanation. Said Ben Azai: I shall explain: If you say “shelishis,” [this means] with respect to others in a count; but if you say “shelashis,” [this means] a 3-year-old.  Similarly, they said: A reva’i vineyard. They said to him: What is this wording “reva’i”? He said to them: This is what I have heard with-out explanation. Said Ben Azai: I shall explain: If you say “revi’i,” [this means] with reference to others in a list; but when you say “reva’i,” it means four years old.  Similarly they said: If someone eats in a tzaraas-afflicted house, half a loaf of three per kav. They said to him: Say “of eighteen to a se’ah!” He said to them: So have I received without explanation. Said Ben Azzai: I shall explain: If you say “of three per kav,” there is no challah; but if you say “of eighteen per se’ah,” its challah portion reduces it.
