If a blind man blinded another's eye, or an amputee cut off another's hand, how would we fulfill "you will do to him like he plotted to do to his brother''? This teaches that he only pays money. (That verse discusses Edim Zomemin. It also says "Ayin Tachas Ayin.'')

(Mishnah): Pain - if he burned him with a spit or nail, even on his fingernail, in a place that does not make a wound...

Question: It says "Keviyah Tachas Keviyah'' - what is the case?

If he bruised him and blood came out, it already says Petza Tachas Petza! If you will say that he made a wound, it already says "Chaburah Tachas Chaburah''! What do we learn from Keviyah Tachas Keviyah?

Rather, he burned him with a spit on his palm, and it swelled, or on his foot and it swelled, or he put on him snow or cold water in a place that is not seen, he pays to him his pain. (We explained this like HAGAHOS R. DINAR.)

(Mishnah): We evaluate how much a person like this would ask to receive in order to be pained this way.

(R. Ze'irah): [This means that] we evaluate a person, and say to him 'how much would you give to avoid this pain?' What he says, [the damager] gives to [the victim].

Objection (Mar Ukva): Our Mishnah says 'how much a person would ask to receive', and you say so?!

Rather, we evaluate a person, and say to him 'how much would you want to receive in order to be pained this way?' What he says, [the damager] gives to [the victim].

(Beraisa - Ben Azai): We give loss of food.

What is loss of food? Initially I used to eat lentils and vegetables. Now I can eat only eggs and chickens. What he says, he gives to him [the added cost of the food he must eat to be cured].

Support (R. Yosi bar Yakov): These Roman [soldiers], when one is ill, he does not go out to fight until he eats what he was lacking, for a number of days corresponding to the days [that he was ill].
