“Let the Dead Bury Their Dead”. Jewish Funerary Customs and Matthew 8:21–22. Funerary customs are inseparable from the fifth commandment. They impose strict obligations on relatives, lasting until the end of a one-year period. The practice of ossilegium, that is, the collection of the bones of the deceased, marks the conclusion of this process. When decomposition completes its cycle, the deceased is “survived”. The buried individual finds comfort in the expiatory disintegration he/she undergoes.
