This is an excerpt from the self help book "Pushing To The Front" by Orison Swett Marden under a chapter entitled "Dare":
As the strongest man has a weakness somewhere, so the greatest hero is a coward somewhere. Peter was courageous enough to draw his sword to defend his Master, but he could not stand the ridicule and the finger of scorn of the maidens in the high priest's hall, and he actually denied even the acquaintance of the Master he had declared he would die for.
I know this is not a grammar question, but I need to know who is 'Peter'. I'm not familiar with history of west.
Thanks
