Shmirah is a Jewish practice that involves watching over and guarding the deceased until burial. This tradition is rooted in the belief that the body should be treated with respect and dignity after death. It often includes reciting prayers and ensuring that the body is not left alone. The person who performs Shmirah is called a Shomer. This role can be filled by family members, friends, or volunteers from the community. The practice is an important part of Jewish mourning customs, emphasizing the value of community support during times of loss.
