A Particular Kind of Umbilical

(19) You shall observe My laws. You shall not let your cattle mate with a different kind (kilayim); you shall not sow your field with two kinds of seed (kilayim); you shall not put on cloth from a mixture of two kinds of material (kilayim sha'atnez).

(5) Mules of uncertain parentage are forbidden [one with another,] And a ramakh is permitted. The Masters of the Field are [in the category of] chayah...

The Masters of the Field - This is a wild animal that grows in the fields, that has a kind of big cord coming out of a root in the earth from where it gets its nourishment. And it is also called the Yadua, for it is the Yidoni written of in the Torah. It is joined from its navel to the cord coming out of the ground, and it appears human in form, in its facial features, arms and legs. And no creature should approach within the length of that cord, for it tears and kills everything that comes close. When people want to hunt it, they shoot arrows from afar at its cord until it is severed, and then it screams out a bitter cry, and dies immediately.

(31) Do not turn to ghosts ('ovot) and do not inquire of familiar spirits (yidonim), to be defiled by them: I the LORD am your God.

§ The Sages taught: A necromancer is one who causes the voice of the dead to be heard speaking from between his joints or from his armpit. A sorcerer [yideoni] is one who places a bone of an animal called a yadua in his mouth, and the bone speaks on its own.
