Exodus 22:27 "Do not curse G-d"
This Negative Mitzvah is often called "Birkat HaShem," which
literally means "blessing HaShem."
We do not even want to call this terrible offense by it's real name - so the
opposite term is used.
We are forbidden to curse HaShem.
This Negative Mitzvah also prohibits one from cursing judges.
We must honor and respect judges and realize that their decisions help us
fulfill the Torah and Mitzvot.
