I know that there are numerous Jewish Laws which in theory are punishable by death but when was the last recorded instance of a death sentence carried out?

The State of Israel has only ever executed one person – Adolf Eichmann – for Crimes Against Humanity in 1962.

Hi,
Thanks for asking this question. The implication of your comment about Adolf
Eichman is correct. We do not carry out the death penalty anymore. As a
matter of fact, Adolf Eichman had nothing to do with the biblical concept of
death penalty. The biblical concept of the death penalty is one that is very
hard to actually carry out. As a matter of fact, our rabbis teach us that a
court that would implement the death penalty once in 70 years would be a
murderous court. According to some commentators it was never carried out.
The purpose of having these laws was to scare one into not sinning in order
to show the grave consequences of our actions. In order to actually carry
out this penalty many things would have to be in place including two
“kosher” witnesses, a warning given to the criminal, and many other things
that are very difficult to actually happen. We do know of death penalty
cases carried out by G-d in the Torah. The Torah was not written in order to
have cruel punishments carried out on the Jews, but rather to outline what
is moral behavior and the punishments simply identify the severity of the
crimes.
Be Well
