The 197th prohibition is that we are forbidden to eat chometz on Pesach.
The source of this commandment is G‑d's statement,1 "No chometz may be eaten."
If chometz was eaten intentionally, the punishment is kores,2 as the verse3 states clearly, "Whoever eats chometz shall receive kores." If it was eaten unintentionally, the person must bring a sin-offering.4
The details of this commandment are explained in tractate Pesachim.
