Yevamot II 70: Who Cannot Partake of Teruma? The Importance of Intact Male Genitals

Our Gemara discussed the Mishna that introduces Yevamot II and Perek VIII.  The Mishna teaches us that:

• regarding an uncircumcised priest and all others who are ritually impure:
• they cannot partake of teruma
• their wives and slaves can partake of teruma
• regarding a priest with petzua dakka, crushed (damaged) testicles or kerut shofcha, a severed penis:
• they and their slaves may partake of teruma 
• their wives may not partake of teruma because priests may not have intercourse with women who are rendered chalalot, and their wives would be rendered chalalot if they had intercourse with anyone with such conditions
• these wives may partake of teruma if they have no sexual contact with their husbands following the injuries, for their marriages were sound
• any damage to even one testicle counts as petzua dakka
• as long as there is one hairbreadth of corona of the penis, it is not considered to be kerut shofcha 

The Gemara begins with a discussion about what is forbidden to hired servants, sojourners, or other 'outsiders' at Pesach when the korban Pesach, the paschal lamb, is shared with the community.   They note who is permitted to partake of the meal and who is not.  In particular they look at those in acute mourning and those who have not been circumcised.  We learn the halacha: hired servants and sojourners are not allowed to partake of teruma, one who is not circumcised is liable to karet (for transgressing a positive mitzvah), and one who does not circumcise his children/slaves may not sacrifice the paschal lamb.

Today's daf does not make the connection between the halacha as determined by the Gemara and the Mishna.  However, we note that the rabbis are attempting to understand other circumstances where an entitlement like teruma - in this case, the paschal lamb - is restricted to certain groups of people.
