Art thou better than No-amon, That was situate among the rivers, That had the waters round about her; Whose rampart was the sea, and of the sea her wall?
Rashi on Nahum
Are you better than No-amon—Why should you rely on your wealth and your might? Are you greater than No-amon? That is, Alexandria of Egypt. Amon is an expression of a pedagogue. [Are you greater] than the great No, which trained the kings of Egypt, for they would anoint the kings there?
Rashi on Nahum
whose wall was the sea to whom the sea was their rampart and their wall. [This mode of construction is known in Aramaic as] שורה ובר שורה, a wall and the son of a wall [referring to a large wall on the outside, opposite an inside of which is built a small wall].
