The primary meaning of the Hebrew word mitzvah ("commandment", Hebrew: מִצְוָה‎‎, [mit͡sˈva], Biblical: miṣwah; plural מִצְווֹת mitzvot [mit͡sˈvot], Biblical: miṣwoth; from צִוָּה ṣiwwah "command") refers to precepts and commandments as commanded by God. It 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 are, or are derived from, divine commandments.

The secondary meaning of 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. The tertiary meaning of mitzvah also refers to the fulfillment of a mitzvah.

The opinions of the Talmudic rabbis are divided between those who seek the purpose of the mitzvot and those who do not question them. The latter argue that if the reason for each mitzvah could be determined, people might try to achieve what they see as the purpose of the mitzvah, without actually performing the mitzvah itself ("Lishma"), which would become self-defeating. 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 (some mitzvot are given reasons in the Torah).

Bernard Jeffrey McCullough (October 5, 1957 – August 9, 2008), better known by his stage name, Bernie Mac, was an American actor and comedian. Born and raised on the South Side of Chicago, Mac gained popularity as a stand-up comedian. He joined comedians Steve Harvey, Cedric the Entertainer, and D. L. Hughley as The Original Kings of Comedy.

After briefly hosting the HBO show Midnight Mac, Mac appeared in several films in smaller roles. His most noted film role was as Frank Catton in the remake Ocean's Eleven and the titular character of Mr. 3000. He was the star of The Bernie Mac Show, which ran from 2001 through 2006, earning him two Emmy Award nominations for Outstanding Lead Actor in a Comedy Series. His other films included starring roles in Booty Call, Friday, The Players Club, Head of State, Charlie's Angels: Full Throttle, Bad Santa, Guess Who, Pride, Soul Men, Transformers and Madagascar: Escape 2 Africa.

Mac suffered from sarcoidosis, a disease in which abnormal collections of chronic inflammatory cells (granulomas) form as nodules in multiple organs, particularly the lungs and lymph nodes. Lung scarring or infection may lead to respiratory failure and death. Mac had said the condition was in remission in 2005. His death on August 9, 2008 was caused by complications from pneumonia.
