Exodus 21:19 (KJV)

But if a man come presumptuously upon his neighbour, to slay him with guile; thou shalt take him from mine altar, that he may die.

And he that smiteth his father, or his mother, shall be surely put to death.

And he that stealeth a man, and selleth him, or if he be found in his hand, he shall surely be put to death.

And he that curseth his father, or his mother, shall surely be put to death.

And if men strive together, and one smite another with a stone, or with his fist, and he die not, but keepeth his bed:

And if a man smite his servant, or his maid, with a rod, and he die under his hand; he shall be surely punished.

Notwithstanding, if he continue a day or two, he shall not be punished: for he is his money.

If men strive, and hurt a woman with child, so that her fruit depart from her, and yet no mischief follow: he shall be surely punished, according as the woman's husband will lay upon him; and he shall pay as the judges determine.

And if any mischief follow, then thou shalt give life for life,

Eye for eye, tooth for tooth, hand for hand, foot for foot,
