Exodus 21:20-22

King James Version

²⁰ And if a man smite his servant, or his maid, with a rod, and he die under his hand; he shall be surely punished.

²¹ Notwithstanding, if he continue a day or two, he shall not be punished: for he is his money.

²² 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.
