> Eidim zom'mim are a particular type of false witnesses, who have been proven false by virtue of testimony that they were not present at the event they claim to have witnessed. If Reuven and Shimon testified, for example, that they saw Levi kill Yehudah, they could be proven to be eidim zom'mim if others testify that they saw Reuven and Shimon in another city on that day. If this happens, Reuven and Shimon are put to death since this is what they tried to have inflicted on Levi. See the next mitzvah, P180 .
