Jebhammoth 61 Best: Keritot 6b Page 78
The crux of the argument in Keritot 6b involves the interpretation of the phrase "mibchar nedercha" ("the choice of your vows") found in Leviticus 27:11 regarding animal offerings. This verse implies that offerings must be of the highest quality ("the best").
The Talmud asks: Does this requirement for "the best" apply to bird offerings as well? If the Zav is obligated to bring "the best," it implies a strict standard. However, the Talmud seeks to define what exactly constitutes "the best" in the context of a bird. Is it age? Is it species?
Here, the Talmud in Keritot turns to the principles established in Yebamoth 61a.
The discussion in Keritot 6a–6b begins with a Mishnah that discusses the varying obligations of a Zav. A Zav who has experienced two discharges is obligated to bring a bird sin-offering. If he experiences a third discharge, his status changes, and his obligation to bring a sin-offering remains.
The Gemara (6a) raises a difficulty regarding the verse that commands the Zav to bring a sin-offering. The Torah states: "And on the eighth day, he shall take for himself two turtledoves or two young pigeons... one for a sin-offering and the other for a burnt-offering" (Leviticus 15:14-15). keritot 6b page 78 jebhammoth 61 best
The question posed in Keritot 6b is one of categorization. The Torah distinguishes between a "rich" and a "poor" offering in other contexts (such as the Metzora in Leviticus 14). However, for the Zav, the Torah specifies birds. Does this mean the Zav is unique, or does he share the legal parameters of other sin-offerings?

Until then, the “best” resolution from traditional lomdus (analytic method) is:
The doubt in Keritot is about the person’s action; the doubt in Yevamot is about the person’s status. Different doubts, different rules. The crux of the argument in Keritot 6b
In the world of Talmudic study, few arguments are as anatomically precise yet spiritually profound as the debate surrounding the verse in Leviticus 3:4 regarding the sacrifices: "And the two kidneys..."
This debate spans two major tractates—Yevamot 61a and Keritot 78a (referenced as 6b in your query regarding the count of organs)—and centers on a fundamental question of biological and metaphysical definition: What actually counts as a "kidney"?
If you are studying the intersection of doubtful sin and forbidden relationships, here is the key takeaway:
Keritot 6b establishes that if a person is unsure whether they committed a karet-level offense (e.g., eating forbidden fat or having relations with a forbidden relative), they must bring a provisional guilt-offering once they become aware of the doubt.
Yevamot 61 establishes the list of women with whom relations are karet-level (e.g., a mother, sister, daughter). The “best” harmonization is: the sacrificial system addresses the individual’s spiritual atonement, while the marriage laws address the social and legal status of any children born from such unions (they become mamzerim).

The Torah commands that the internal fat and the "two kidneys" (shetei klayot) of a sacrificial animal be burned on the altar. If one fails to burn these specific organs, the sacrifice is invalid.
This creates a strict legal requirement: To fulfill the Mitzvah, you must know exactly where the kidney begins and ends.
The tractate of Keritot deals with sins that incur the penalty of Karet (spiritual excision) and the requisite sin offerings. Here, the precision of the sacrifice is paramount. If you offer a kidney, you must offer the whole kidney.
The Question: The Kidney is not a smooth, round ball; it is lobed. It has a cortex (outer layer) and a medulla (inner structure). The Torah says "two kidneys"—does this mean two physical organs, or does the internal structure change the count?
The Argument: The Gemara in Keritot engages in a "Sifra" (Halachic exegesis) debate:
