Mishnah Pesachim 9:7 - Why does the registration of an inherited Paschal Lamb not automatically get assigned to a father's son?
In the Mishnah Pesachim 9:7, we read :
"With regard to one who separates his Paschal lamb and then dies, his son may not bring it after him for the purpose of a Paschal lamb because it may no longer be used for that purpose after its owner has died." ( הַמַּפְרִישׁ נְקֵבָה לְפִסְחוֹ אוֹ זָכָר בֶּן שְׁתֵּי שָׁנִים, יִרְעֶה עַד שֶׁיִּסְתָּאֵב, וְיִמָּכֵר, וְיִפְּלוּ דָמָיו לִנְדָבָה. הַמַּפְרִישׁ פִּסְחוֹ וָמֵת, לֹא יְבִיאֶנּוּ בְנוֹ אַחֲרָיו לְשֵׁם פֶּסַח, אֶלָּא לְשֵׁם שְׁלָמִים )
The mishnah teaches that even the son who inherits from his father cannot offer it as a pesah. **In other words the son does not inherit his father’s registration for that sacrifice.** Therefore it is sacrificed as a sacrifice of wellbeing.
- Why was this decision established? (Would the desire for registration fees be the cause of this law?)
