Exodus 21:19-24

19then if the man rises again and walks outdoors with his staff, he who struck him shall be clear; only he shall pay for the loss of his time, and shall have him thoroughly healed.

20"When a man strikes his slave, male or female, with a rod and the slave dies under his hand, he shall be avenged.

21But if the slave survives a day or two, he is not to be avenged, for the slave is his money.

22"When men strive together and hit a pregnant woman, so that her children come out, but there is no harm, the one who hit her shall surely be fined, as the woman's husband shall impose on him, and he shall pay as the judges determine.

23But if there is harm, then you shall pay life for life,

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