Halakhah sa Exodo 21:9: Sefer HaChinukh & Mishneh Torah, Positive Mitzvot

Not to reduce her flesh, covering and time period: That anyone who acquires a Hebrew bondwoman and designates her may not reduce her flesh, her covering and her time period. And the explanation (Ketuvot 47b) of “flesh” is food, of “covering” is like its simple understanding and of “time period” is the way of the world (conjugal rights). And included in this negative commandment are all daughters of Israel (as well), not to reduce from them any thing from these [categories]. [This inclusion] is a fortiori (kal ve’chomer): If he does not reduce for [bondwomen], all the more so for free [women]. And [about] that which it is written (Exodus 21:9), “like the statute of the daughters he shall do for her” — they said in the Mekhilta DeRabbi Yishmael 21:9:2 that it came to learn [from the others], but it ends up to teach, as the [law of the other] daughters are learned from her.

To espouse a Hebrew maid-servant, as it is said, “(If she please not her master) who hath not espoused her, (then he shall let her be redeemed, and if he espouse her to his son….)” (Ex. 21:8-9).

To adjudge a thief to pay compensation, or (in certain cases) suffer death, as it is said, “If one steals an ox or an ass….” (Ex. 21:37); “If a thief is found breaking in….” (Ex. 22:1); “And he that stealeth a man and selleth him….” (Ex. 21:16).
