Pesachim 92b-93b
If Pesach Rishon was forfeited, a second opportunity to bring the Pascal offering on Sheni is given • Is this forfeiture irrevocable, or can Pesach Rishon be salvaged? • How do women relate to Pesach Sheni? • Kareis, spiritual excision, is only applicable to willful violations of certain laws • When is Kareis applicable to Pesach Rishon and Sheni? • One who becomes an adult between the Pesachim and participated in Pesach Rishon is not required to bring on Pesach Sheni • What is the halacha for a minor who has eaten matzah and then becomes an adult during seder night, must he eat more matza?
