And the 67th mitzvah is that we are commanded to bring a meal-offering in the manner described in the Torah for each particular category.

The sources of this commandment are G‑d's statements,1 "If a person offers a meal-offering to G‑d..."; "If he offers a meal-offering [baked in an oven] ..."; "If it is a meal-offering fried in a pan..." "If it is a meal-offering prepared in a deep pot..." In completing the description, the Torah adds,2 "This is the law of the meal-offering..."

The details of this mitzvah with its numerous subdivisions are explained in the tractate devoted to this subject, tractate Menachos.
