If there is someone who is unsure whether something will prevent them from being able to eat the sacrifice at night, can they be included in the sacrificing of the animal? The mishna describes various cases like this. Can one slaughter a Pesach sacrifice for one individual? Who can make up a group for Pesach – what combinations of people are not permitted? Why? Are women obligated in Pesach or in Pesach Sheni? Is it obligatory, optional, not allowed? Three opinions are brought and the gemara explains where in the verses they derive their positions. Pesach, matza and marror are obligatory on the first night only. Women are obligated in matza and marror as men – why?
