Exodus 21:23

But if there is serious injury, then you will give a life for a life,

You must not show pity; the principle will be a life for a life, an eye for an eye, a tooth for a tooth, a hand for a hand, and a foot for a foot.

If a man inflicts an injury on his fellow citizen, just as he has done it must be done to him --

Moreover, you must not accept a ransom for the life of a murderer who is guilty of death; he must surely be put to death.
