Side-ring EXTRA · Joint address for zav law
Same pattern as 14:33 and other openings to Moshe and Aharon; classical treatment that impurity/purity declarations involving the kohen are framed jointly.
English: “Hashem spoke to Moshe and to Aharon” — in the laws of flux, keri, and niddah as well, the kohen is partnered in the speech, for from him the laws of purity are learned.
Kohen in emissions law
Chapter 15 opens with the same dual address as the house-nega section, marking a new body of purity law in which the kohen’s role remains central.
