Bereavement in Judaism () is a combination of minhag (traditions) and mitzvah (commandments) derived from the Torah and Judaism's classical 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 specific to an individual mourning a parent.
Religious laws concerning mourning do not apply to those under thirteen years of age, nor do they apply when the deceased is aged 30 days or less.
Upon receiving the news of the death, the following blessing is recited:
ברוך אתה יה אלוהינו מלך העולם, דיין האמת
Barukh atah Adonai Eloheinu melekh ha'olam, dayan ha-emet. ("Blessed are You, Lord, our God, King of the universe, the True Judge.")
In the Tanakh (Jewish Bible) the custom was to tear one's clothes at the moment one heard news of a death. The modern practice is for the close relatives who are the principal mourners to tear their clothing at the funeral.
