Exodus 21:19-24

19— if he rise, and walk abroad upon his staff, then shall he that struck [him] be guiltless; only he shall pay [for] the loss of his time, and shall cause [him] to be thoroughly healed.

20And if a man strike his bondman or his handmaid with a staff, and he die under his hand, he shall certainly be avenged.

21Only, if he continue [to live] a day or two days, he shall not be avenged; for he is his money.

22And if men strive together, and strike a woman with child, so that she be delivered, and no mischief happen, he shall in any case be fined, according as the woman's husband shall impose on him, and shall give it as the judges estimate.

23But if mischief happen, then thou shalt give life for life,

24eye for eye, tooth for tooth, hand for hand, foot for foot,
