Pesachim 7:13-8:1
Pesachim 7:13
If two groups were eating their Passover offerings in the same house they may face in different directions to eat with the water to dilute the concentrated wine between them. When the waiter gets up to mix the wine, he must close his mouth and turn his face away until he returns to his own group (so that he will not appear to be eating with the other group). A bride (who is embarrassed to eat in front of others) may turn aside to eat the Passover offering and she is still considered to be eating with her group.
Pesachim 8:1
If a woman is in her husband’s house (as opposed to her father’s house) and both her husband and her father slaughtered the Passover offering with her in mind, she eats with her husband. If she went to spend her first holiday married at her father’s house and both her husband and her father slaughtered the Passover offering with her in mind, she eats with whomever she chooses. An orphan whose guardians slaughtered the Passover offering for him may eat wherever he chooses. A slave with two masters may not eat from either of their offerings (unless he has the other’s permission). A person who is half-slave and half-free may not eat from his master’s offering (because of his partial freedom).
