Halakhah sa Exodo 22:18: Tur & Mishneh Torah, Negative Mitzvot

Not to lie with an animal: It is prohibited to lie with an animal, as it is stated (Leviticus 18:23), "And with every beast do not give your lying." We learn in Sanhedrin (54b) that this also includes a warning for the one lying, from the expression "your lying," which implies also his lying, with the punishment of stoning, as it is said, "And a man who gives his lying to a beast shall surely be put to death, and you shall kill the beast." We find in the case of the seducer who is stoned that it is written there, "For he killed him," and it also says, "And a woman who approaches any beast to mate with it, you shall kill the woman and the beast; they shall surely be put to death, their blood is upon them." From there we learn the punishment for the one lying and the punishment for the one lying with it. How do we know this? The Torah says (Exodus 22:18), "Whoever lies with a beast shall surely be put to death." If it is not relevant for the one lying, since we have already learned this, teach it in relation to the one lying with it. And the expression "lying" is written to interpret that the one lying is punished with stoning. Therefore, I would say that this is the death mentioned in the Torah, which is strangulation, and one could question why the punishment for the one lying is not learned from the expression "your lying," which implies also his lying. And there is no distinction between a large animal and a small one.

Not to slaughter the Paschal lamb while there is leaven in the home, as it is said, “Thou shalt not offer the blood of my sacrifice with leaven” (Ex. 23:18 and 34:25).

Not to suffer any one practising witchcraft to live, as it is said, “Thou shalt not suffer a witch to live” (Ex. 22:17).
