Exodus 21:22-25 NIV

[22] “If people are fighting and hit a pregnant woman and she gives birth prematurely but there is no serious injury, the offender must be fined whatever the woman’s husband demands and the court allows. [23] But if there is serious injury, you are to take life for life, [24] eye for eye, tooth for tooth, hand for hand, foot for foot, [25] burn for burn, wound for wound, bruise for bruise.
