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 Ex12-42c URL Reference: (c) http://www.Rashiyomi.com/w35n4.htm Brief Summary: This night (Passover) is the WATCHED NIGHT for all generations. God always protects Jews on Exodii.

Verse Ex12-42c discussing the exodus of the Jews from Egypt states It is a night of watchfulness to the Lord for bringing them out of the land of Egypt. This is a night of watching kept to the Lord by all the people of Israel throughout their generations. Rashi notes that the underlined words, night of watchfulness....throughout their generations references verses Ex12-23 discussing God's smiting the Egyptian first born but sparing the Jewish first born. Hence the Rashi comment Just as God watched the Jews when they left Egypt - the Egyptians were being smitten but the Jews were left alone - so too for all generations. Whenever the Jews exodus a tyrannical country God will simultaneously protect them while hurting their enemies.

Text of Target Verse Ex12-42c	Text of Reference Verse Ex12-23
It is a night of watchfulness to the Lord for bringing them out of the land of Egypt. This is a night of watching kept to the Lord by all the people of Israel throughout their generations.	For the Lord will pass through to strike the Egyptians; and when he sees the blood upon the lintel, and on the two side posts, the Lord will pass over the door, and will not let the destroyer come into your houses to strike you
Rashi comments: Just as God watched the Jews when they left Egypt - the Egyptians were being smitten but the Jews were left alone - so too for all generations. Whenever the Jews exodus a tyrannical country God will simultaneously protect them while hurting their enemies

Advanced Rashi: Rashi literally says It is watched from damaging spiritual forces as it says in Ex12-23 ....he will not let the destroyer come to Jewish houses. There are a variety of ways to interpret this: a) It could refer to a special quality of Nissan 14th; b) it could refer to the absence of demonic spiritual agents on this night. I would suggest a different approach and focus on Rashi's citation ....and I God will not allow the destroyer to come to Jewish houses... Thus I think it best to interpret the verses naturally: ....This night of Passover is watched [by the Jews! as a holiday so that] For all generations, whenever God takes the Jews out of danger there will be simultaneous destruction of enemies but protection of Jews. In other words I interpret the verse as indicating that the Passover exodus is archetypical - God protects us even while destroying our enemies. This is an important point - for we Jews would obviously be very vulnerable when leaving if God is bringing a plague. The non Jews might retaliate. Therefore we are promised that God's attack on our enemies will be coupled with our own protection and salvation.
