- Eye for an eye (Wikipedia)
“An eye for an eye” (Biblical Hebrew: עַיִן תַּחַת עַיִן, ʿayīn taḥaṯ ʿayīn) is a commandment found in the Book of Exodus 21:23–27 expressing the principle of reciprocal justice measure for measure. The earliest known use of the principle appears in the Code of Hammurabi, which predates the writing of the Hebrew Bible but not necessarily oral traditions.
