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 Ex10-13a URL Reference: (c) http://www.Rashiyomi.com/rule1324.htm Brief Summary: (Ex10-13a) ...An EAST WIND carried the locust RASHI: The locust came FROM Israel to EGYPT which was in the SOUTHWEST of Israel (Nu34-03:05)

Verse Ex10-13a discussing the 8th plague, the locusts, states And Moses stretched forth his rod over the land of Egypt, and HaShem brought an east wind upon the land all that day, and all the night; and when it was morning, the east wind brought the locusts. Rashi notes that the underlined words, east wind references verses Nu34-03:05 discussing the southern borders of Israel. Hence the Rashi comment Verse Ex10-13a states that the locusts were brought from Israel to Egypt by an east wind. This references Nu34-03:05 which describes the southern border of Israel and explicitly states that Egypt is on the southwest of Israel (and hence an Eastern wind is needed to transport locusts there).
