וינזרו THAT THEY KEEP AWAY [FROM THE HOLY THINGS etc.] — The term נזר always denotes “keeping aloof". Similarly it is said (Ezekiel 14:7) "and he separates himself (וינזר) from following Me”; (Isaiah 1:4) "They are gone away (נזורו) backward”. The meaning of this verse therefore is: they (the priests) shall keep aloof from the holy things during the time of their uncleanness (Sifra, Emor, Section 4 1).

What does the word Rav add to this verse that the words Gadol and Atzum have not already taught us?
