Exodus 21:20-23

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

22If men shall contend, and hurt a woman with child, so that her fruit shall depart from her, and yet no harm 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 harm shall follow, then thou shalt give life for life,
