Of the six that are listed, this was the only one I was familiar with, and thought was true.
The high priest tied a rope around his ankle so that others could drag him out of the Holy of Holies in case God struck him dead.
Various versions of this claim have been repeated by pastors, but it is a legend. It started in the Middle Ages and keeps getting repeated. There is no evidence for the claim in the Bible, the Apocrypha, the Dead Sea Scrolls, Josephus, the Pseudepigrapha, the Talmud, Mishna or any other source. Furthermore, the thickness of the veil (three feet) would have precluded the possibility of a priest being dragged out anyway.
