In its primary meaning, the Hebrew word mitzvah (“commandment”, מִצְוָה, plural מִצְווֹת mitzvot [mitÍ¡sˈvot], Biblical:”command”) refers to precepts and commandments as commanded by God. 

The word mitzvot or Mitzvah also meaning; to connect to God via the fulfillment of doing, keeping and practicing the moral laws of Torah.


To connect to one’s true human nature to God via the act of fullfiling a Mitzvah.

He who does a mitzvah (God’s holy commandment), connects and relates his or her seven emotions – emotions and intellect to God’s knowledge, revelation, holiness and presence.


The holy acts of prayer, tithing, charity, marriage, Torah learning or studies, the keeping of the Sabbath, the keeing of God’s feasts as in Leviticus 23:1-44, are all considered as mitzvot, (agents which enables humans beings to connect to God via the frequent act of practicing those mitzvot).


Mitzvah is a word used in Judaism to refer to the 613 commandments given in the Torah (at Mount Sinai, where all the Jews accepted the Torah, saying “We will do, and we will listen”) and the seven rabbinic commandments instituted later for a total of 620. 

According to the teachings of Judaism, all moral laws (philanothropic ides) are derived from the divine holy commandments of the Torah.


In its secondary meaning, Hebrew mitzvah, as with English “commandment,” refers to a moral deed performed as a religious duty. 
As such, the term mitzvah has also come to express an act of human kindness (philanonthropy). 

The former believe that if people were to understand the reason and the purpose for each mitzvah, it would actually help them to observe and perform the mitzvah.
