The 330th prohibition is that one is forbidden from having relations with one's mother.
The source of this commandment is G‑d's statement,1 "She is your mother; you must not commit incest with her."
The punishment for violating this prohibition is kares.2 If there were witnesses, and the act was intentional, the punishment is execution by stoning.3 If the act was unintentional, he must bring a sin-offering.4
