The 226th mitzvah is that we are commanded to execute by the sword1 those who transgress certain mitzvos.

The source of this commandment is G‑d's statement2 (exalted be He), [the death] "must be avenged."

In our list of the prohibitions we will point out which mitzvos are punishable by decapitation.

The details of this mitzvah are explained in the 7th chapter of tractate Sanhedrin.
