where does the eye for an eye come from
Eye for an eye First referenced in the Code of Hammurabi, (which predates the Hebrew bible.) In the Hebrew Law, the "eye for eye" was to restrict compensation to the value of the loss. Thus, it might be better read 'only one eye for one eye'.[3] The biblical phrase "an eye for an eye" in Exodus and Leviticus (עין תחת עין‬, ayin tachat ayin) literally means 'an eye in place of an eye' while a slightly different phrase (עַיִן בְּעַיִן שֵׁן בְּשֵׁן, literally "eye for an eye; tooth for a tooth") is used in another passage (in Deuteronomy) of the Hebrew Bible, specifically, in the first of its three subdivisions, the Torah.[9][10][11] For example, a passage in Leviticus states, "And a man who injures his countryman – as he has done, so it shall be done to him [namely,] fracture for fracture, eye for eye, tooth for tooth. Just as he has injured a person, so it shall be done to him." (Lev. 24:19–21)[9]
Sauron Throughout The Lord of the Rings, "the Eye" (the Red Eye, the Evil Eye, the Lidless Eye, the Great Eye) is the image most often associated with Sauron. Sauron's Orcs bore the symbol of the Eye on their helmets and shields, and referred to him as the "Eye" because he did not allow his name to be written or spoken, according to Aragorn[54] (a notable exception to this rule was his emissary, the Mouth of Sauron). Also, the Lord of the Nazgûl threatened Éowyn with torture before the "Lidless Eye"[55] at the Battle of the Pelennor Fields.
