Exodus 21:20-23

20And if a man smite his servant, or his maid, with a rod, and he die under his hand; he shall be surely punished.1 21Notwithstanding, if he continue a day or two, he shall not be punished: for he is his money.

22If 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. 23And if any mischief follow, then thou shalt give life for life,
