the requirement of Priests to wash their
hands and legs
when they go into the tent of meeting, they shall wash with water, that they die not; or when they come near to the altar to minister, to cause an offering made by fire to smoke unto HaShem;
Rashi on this verse makes a simple logical inference:
As shown by the underlined words the verse shows that
if they wash they die not. From this we infer that
if they serve in the temple without first washing their
hands and legs that they deserve to die.
The use of logic to make a simple inference is classified
by us as a NonVerse method because no inference is
made from other verses, word meaning, grammar, or
style. Rather the meaning is logical and
literally non verse.
