1. RASHI METHOD: REFERENCES BRIEF EXPLANATION: Commentary on a verse is provided thru a cross-reference to another verse. The cross references can either provide (1a) further details, (1b) confirm citations, or (1c) clarify word meaning. This examples applies to Rashis Dt02-16c URL Reference: (c) http://www.Rashiyomi.com/w34n5.htm; Brief Summary: The MEN OF WAR mentioned in Dt02-16 refers to 20+ year olds Nu14-29 on whom death was decreed. 20+ is military age (e.g. Nu01-20)

Verse Dt02-16, discussing the death of the men of war states So it came to pass, when all the men of war had completed dying from the people, Rashi clarifies the underlined words men of war by referencing verse(s) Nu14-29,Nu01-20 discussing the death decree on those who accepted the slander of the spies which states Your carcasses shall fall in this wilderness; and all who were counted of you, according to your whole number, from twenty years old and upward, who have murmured against me ....And the sons of Reuben, Israel's eldest son, by their generations, according to their families, by the house of their fathers, according to the number of the names, by their polls, every male from twenty years old and upward, Hence the Rashi comment: The men of war mentioned in Dt02-16 refers to the 20+ year olds who accepted the slander of spies on whom was decreed death. These 20+ year olds are called men of war since 20 is the age of military conscription (Nu01-20).

Text of Target verse Dt02-16	Text of Reference Verse Nu14-29,Nu01-20
So it came to pass, when all the men of war had completed dying from among the nation,	Your carcasses shall fall in this wilderness; and all who were counted of you, according to your whole number, from twenty years old and upward, who have murmured against me ....And the sons of Reuben, Israel's eldest son, by their generations, according to their families, by the house of their fathers, according to the number of the names, by their polls, every male from twenty years old and upward,
Rashi comments: The men of war who died mentioned in Dt02-16 refers to the 20+ year olds who accepted the slander of spies on whom was decreed death. These 20+ year olds are called men of war since 20 is the age of military conscription (Nu01-20).

Advanced Rashi: Note the unusual feature that we have a nested reference, in the above example. Men of war who died references the 20+ year olds on whom was decreed death and 20+ year olds references the census where we are told that 20 is the age of military conscription.

We will revisit this example below in rule #3, grammar.
