Yahrtzeit

Bereavement in Judaism (Hebrew: אֲבֵלוּת, avelut; mourning) is a combination of minhag and mitzvah derived from Judaism's classical Torah and rabbinic texts. The details of observance and practice vary according to each Jewish community.

In Judaism, the principal mourners are the first-degree relatives: parent, child, sibling, and spouse. There are some customs that are unique to an individual mourning a parent.

Halachos concerning mourning do not apply to those under thirteen years of age. Also, halachos of mourning do not apply when the deceased is aged 30 days or less.

Upon receiving the news of the passing, the following blessing is recited:

There is also a custom of rending one's clothes at the moment one hears news of a passing. Another prevalent custom is to tear at the funeral so that the procedure is done properly.

The chevra kadisha (חברה קדישא "holy society") is a Jewish burial society usually consisting of volunteers, men and women, who prepare the deceased for proper Jewish burial. Their job is to ensure that the body of the deceased is shown proper respect, ritually cleansed, and shrouded.

Many local chevra kadishas in urban areas are affiliated with local synagogues, and they often own their own burial plots in various local cemeteries. Some Jews pay an annual token membership fee to the chevra kadisha of their choice, so that when the time comes, the society will not only attend to the body of the deceased as befits Jewish law, but will also ensure burial in a plot that it controls at an appropriate nearby Jewish cemetery.

If no gravediggers are available, then it is additionally the function of the male society members to ensure that graves are dug. In Israel, members of chevra kadishas consider it an honor to not only prepare the body for burial but also to dig the grave for a fellow Jew's body, particularly if the deceased was known to be a righteous person.
