Neither of which is prescribed in the Mosaic Law. There were no physical punishments for economic crimes, which required multiple reimbursement, a policy that actually makes sense. You steal $100 from me, you have to pay me back some multiple of that amount. If you can't pay, you're sold into slavery, or more accurately indentured servitude, until the amount has been worked off.
It is interesting that you make no attempt to explain WHY "an eye for an eye" is unjust. I am perfectly well aware that we don't do it that way here. Do you seriously contend that our present criminal system is the best that could possibly be implemented?
Would you rather be flogged and spend a week in the hospital or be locked up in a prison and perhaps raped hundreds or thousands of times in a year? That's the way our "kinder and gentler" system often works in practice.
I believe that much of the opposition to "an eye for an eye" is based on squeamishness, not logic.
