avraham y. berger asks:
in regards to our sugia [and in general] why is he treated as in a different category than a gair
avraham y. berger, lakewood,n.j.
The Kollel replies:
There is in fact no difference between the freed Eved and the Ger. The Mishnah tells us that a non-freed Eved is exempt from being seen in the Beis ha'Mikdash, which implies that a freed Eved is obligated. A Ger is also obligated.
A Chiger is exempt because he is lame and is not capable of walking up to Jerusalem.
Kol Tuv,
