Maaser (tithe) is one of the most extraordinary Mitzvot that were given to the Jewish people. It is thanks to it that since 3,300 years, Jews have expressed the goodness that characterizes and distinguishes them from other nations. It is also through its merit that the Torah survived the vicissitudes, which unfortunately enamelled our history.
