Q&A: Derived from What Is Itself Derived
Derived from What Is Itself Derived
Question
Do you have an explanation for why throughout the Torah we derive from something that is itself derived, but in the realm of sacrificial matters we do not?
Answer
Maybe this will help you regarding the distinctiveness of the realm of sacrificial matters, in my article here:

or in column 556.
True, there I dealt with “Scripture repeated it to make it indispensable,” which also characterizes the realm of sacrificial matters. As for deriving from what is itself derived, I don’t know. I’d have to think about it. Of course, this is said only about certain pairs of hermeneutic principles, not every case of deriving from what is itself derived, so it probably depends on the type of principles involved and not simply on the difference between sacrificial and non-sacrificial matters.
I now saw brief explanations here along mystical lines. I haven’t checked whether they’re worth anything.
Beyond that, as is known, there are disputes over whether this also exists in non-sacrificial matters (see Mishneh LaMelekh, Laws of the Impurity of Leprosy), and in the Jerusalem Talmud it also seems that it applies in non-sacrificial matters.
I again saw here that he lists several suggestions: https://www.etzion.org.il/he/talmud/seder-kodashim/massekhet-zevachim/%D7%96%D7%91%D7%97%D7%99%D7%9D-%D7%9E%D7%98-%E2%80%93-%D7%9C%D7%9E%D7%99%D7%93%D7%99%D7%9F-%D7%9C%D7%9E%D7%93-%D7%9E%D7%9C%D7%9E%D7%93
