The Hebrew word mitzvah describes the charitable good deed often chosen as a bar or bat mitzvah service project.
In Jewish thought, mitzvah literally refers to a commandment, especially a commandment in the Torah. In ordinary English, however, it is also widely used for a good deed or an act of kindness. A young person may connect the ceremony with a mitzvah project supporting food banks, hospitals, shelters, environmental causes, or other community needs.
A mitzvah project is not a required component of every bar or bat mitzvah. It is a modern educational and charitable practice adopted by many families and congregations. The project can involve volunteering, fundraising, advocacy, or sustained personal action.
The word should not be confused with tzedakah, which specifically concerns charitable giving and justice. Tzedakah may be one form of mitzvah, while mitzvah has a broader meaning that includes many religious obligations and good actions.
