Parashas Metzora · Passuk 15:32
Chabad.org — English translation + Rashi
Torah Temima points to Toras Kohanim.
English: “This is the Torah of the zav” — [and adjacent to it “and one from whom shichvas zera goes out,” the zav is equated to a baal keri]: just as a baal keri immerses by day, so a zav immerses by day.
Daytime immersion for the zav
Chazal equate the zav to a baal keri regarding daytime immersion.
