Judaism: number of Mitzvot in each Torah Book
Of these commandments, 248 are positive; meaning they are actions to be performed, while 365 are negative; meaning they are actions to be avoided. A large number of the Mitzvot are no longer possible to perform, as many are rules relating to the Temple of Jerusalem; the first of which was destroyed by the Babylonians in the 6th century BCE; while the second was destroyed by the Romans in the 1st century CE. Many of the other Mitzvot have limitations based on gender, location, timing, or they are situational. By most accounts, it is believed that only 271 Mitzvots can be observed today, but again, many are dependent on the circumstances or individual.
