At Leviticus 24:17-20 we read:

Here again a similar attitude is shown on the part of the offender​—a deliberate act of murder, or of maiming or injuring a fellowman. Why can we say “deliberate”? Because an unintentional manslayer (someone killing a person accidentally) could receive mercy. “Refuge cities” were provided as sanctuary when the killing was an accident.​—Num. 35:11-15, 25.

And in case a man should cause a defect in his associate, then just as he has done, so it should be done to him.
