English: “Leaven you shall not turn into smoke” — I have only the whole; from where a part? The verse says “every.” From where a mixture? The verse says “for every.”
In the sugya: Successive expansions from the doubled language of “every” bring partial amounts and mixtures under the ban.
Type of Learning
Ribbuy from kol and ki kol — part and mixture are included in the fire-ban.
What Is Learned
Even a small amount of seor, or seor mixed into other material, may not be burned as an isheh to Hashem. The Torah’s successive “every” and “for every” expand the prohibition from the whole to any partial quantity or mixture.
