An eye for an eye?

This is a reference to the bible verse that says something along the lines of "an eye for an eye makes the whole world blind" I don't know the chapter and verse, but I believe it is found in the new testament.

It is also sometimes used today in the shortened form "eye for an eye" to demonstrate stupidity and foolishness, especially in situations of anger and rash/hasty action, and as an admonishment to be more wise.

[In regards to the above response]: "An eye for an eye makes the whole world blind" is NOT a verse in the New Testament. That is a quote that was originated by William Shakespeare, and later reiterated by Mahatma Gandhi. The Biblical reference to "an eye for an eye" is found in the Mosaic Law of the Old Testament (Leviticus), regarding the punishment of crime amongst the Israelite tribes, in accordance with the Covenant of the Law.
