Exodus 21:19-24

19if he gets up and walks around leaning on his cane, then the one who struck him shall be left [physically] unpunished; he must only pay for his loss of time [at work], and the costs [of treatment and recuperation] until he is thoroughly healed.

20“If a man strikes his male or his female servant with a staff and the servant dies at his hand, he must be punished.

21If, however, the servant survives for a day or two, the offender shall not be punished, for the [injured] servant is his own property.

22“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.

23But if there is any further injury, then you shall require [as a penalty] life for life,
