What is Brit Periah?
1.
The very important part of the brit millah added around 140 AD where the mohel uses his inch long fingernails to rip the foreskin from the glans of the infant so that at least 50% of the skin on the penis can be cut off, thus preventing a Jewish boy from ever being able to pull enough foreskin forward to pretend he is not Jewish.
The mohel inserted his dirty finger nail under the foreskin of the baby and brit periah ripped it from the glans as one would rip open the eyes of a puppy or a kitten.
The term Perry Knife comes from this
