OK.. I am innocent. I dont know what the significance of a red heifer is. What is it
As I just posted above...
The Red Cow is needed for the purification ritual... We are all impure from contact with the Dead... The Torah proscribes the way to remove this impurity...
We must have a completely red cow, he will be slaughtered, he will be burned with certain other substances and the ashes mixed with water.. This mixture will be sprinkled by the Kohen on the impure individual... The impure person will become purified while the Kohen applying it will become impure...
This law is one of the laws called "Chukim" meaning that the way it works is not known to us.. It is considered a super-rational law...
