Second Section – the Negative Commandments
4. It is a negative commandment not to eat chametz (bread products) on Passover
As it states in Shemos (Exodus) 13:3, “Do not eat chametz.” Even deriving benefit from chametz is forbidden. Regarding a person that eats an olive size amount of chametz on Passover: If he does it willingly and knowingly, he is punished with kares (premature death). If he does it accidentally, he is required to bring a sin offering [during the time when the Temple stood]. This applies if one eats it or if he crushes it to drink it. If a person eats less than an olive amount, he gets Rabbinic lashes.
This applies in all places and at all times, for men and for women.
4. Be kind to yourself. Speaking badly even about yourself is unethical.
