defilement

"The Highest Mitzvah of All!"

In parashat Emor, our sages derive from the laws governing the prohibition of the priest from defiling himself to the dead, the special commandment of "Met Mitzvah," the requirement to bury an abandoned body for which there is no one else to care. It is considered by many to be the foremost mitzvah, over which no other mitzvah takes precedence.
