Leviticus 20:16

And if a woman approach unto any beast, and lie down thereto,
&c.] In order that the beast may lie with her, and solicit it to commit such an action with her, see ( Leviticus 18:23 ) ; thou shall kill the woman and the beast:
the woman by stoning, and the beast with clubs, as the Targum of Jonathan; and this for the same reasons as before, as well as to prevent monstrous births: they shall surely be put to death;
both the one and the other, and not spared: their blood [shall be] upon them;
they are guilty of a capital crime, a crime which deserves death; this must be understood of the man that lies with a beast, and of the woman; for as for the beast itself, as it is not capable of sinning, so not of guilt, in a proper sense.
