Exodus 21:22-25

“If men fight with each other and injure a pregnant woman so that she gives birth prematurely [and the baby lives], yet there is no further injury, the one who hurt her must be punished with a fine [paid] to the woman’s husband, as much as the judges decide. But if there is any further injury, then you shall require [as a penalty] life for life, eye for eye, tooth for tooth, hand for hand, foot for foot, burn for burn, wound for wound, bruise for bruise.
