Exodus 21:25 (KJV)

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,

And if a man smite the eye of his servant, or the eye of his maid, that it perish; he shall let him go free for his eye's sake.

And if he smite out his manservant's tooth, or his maidservant's tooth; he shall let him go free for his tooth's sake.

If an ox gore a man or a woman, that they die: then the ox shall be surely stoned, and his flesh shall not be eaten; but the owner of the ox shall be quit.

But if the ox were wont to push with his horn in time past, and it hath been testified to his owner, and he hath not kept him in, but that he hath killed a man or a woman; the ox shall be stoned, and his owner also shall be put to death.

If there be laid on him a sum of money, then he shall give for the ransom of his life whatsoever is laid upon him.
