This examples applies to Rashis Dt32-43c URL Reference: (c) http://www.Rashiyomi.com/rule1309.htm Brief Summary: The promise (Dt32-43) that God will avenge Jewish blood is e.g. fulfilled by the desolation of Edom/Egypt for their attacks on Jews Jo04-19

Verse Dt32-43 discussing God's vengenance on those who spilled Jewish blood states Rejoice, O you nations, with his people; for he will avenge the blood of his servants, and will render vengeance to his adversaries, and will make expiation for the land of his people. Rashi notes that the underlined words, for he will avenge the blood of his servants, and will render vengeance to his adversaries, references verses Jo04-19 discussing the destruction of Edom and Egypt as a punishment for the Jewish blood spilt by them. Hence the Rashi comment The vengenance on the adversaries of the Jews who spilt their blood mentioned in Dt32-43 is illustrated by the destruction of Egypt and Edom who spilt Jewish blood (Jo04-19)

Rashi comments: The vengenance on the adversaries of the Jews who spilt their blood mentioned in Dt32-43 is illustrated by the destruction of Egypt and Edom who spilt Jewish blood (Jo04-19)

Advanced Rashi: This example is an instructive illustration of the reference method. For we fully understand the target verse Dt32-43. Furthermore, Rashi is not exhausting the meaning of this verse with the examples of Edom and Egypt. Indeed, Rashi is simply using Jo04-19 as one possible illustration of the content of Dt32-43. So indeed this is an excellent example of how the purpose of reference is not only to explain but also to illustrate.
