luka bakar ganti luka bakar, luka berdarah ganti luka berdarah, memar ganti memar.
Mishneh Torah, One Who Injures a Person or Property
And from where [do we know] that that which it states with regards to limbs, "An eye for an eye," is [to be understood as] payments? Since it is stated about it, "A wound for a wound," and it is explicitly stated, "And when a man strikes his neighbor with a stone or with a fist, etc... he should surely give him his rest and his rehabilitation." Behold, you have learned that "for (tachat)" mentioned with regards to a wound means payments. And this is [also] the case with "for (tachat)" mentioned concerning the eye and concerning the other limbs.
