Bekhorot 42 – בכורות מ״ב | Daf Yomi with Rashi, Tosafot, the Rambam and halacha
What Bekhorot 42 teaches
- The Gemara amends multiple baraitot to omit the tumtum, treating it as an unresolved doubt rather than a distinct entity.
- Unlike humans, an animal with concealed organs is determined male or female based on where it urinates.
- Because a tumtum is physically abnormal, Sages debate whether to suspect further internal mutations like inverted organs or congenital sterility.
The sugyot
- The Gemara examines whether a טוּמְטוּם is an unresolved doubt or an excluded entity, ultimately testing urination signs and the principle הוֹאִיל וְאִישְׁתַּנִּי אִישְׁתַּנִּי.
Halachot from the daf
