(Exodus 15:22) "And they went out to the desert of Shur": This is the desert of Kazav. They said about the desert of Kazav that it was nine hundred parasangs by nine hundred parasangs, all full of serpents and scorpions, viz. (Devarim 8:15) "… who led you in the great, awesome desert of snake, fiery serpent, and scorpion, etc." And it is written (Isaiah 21:1) "A prophecy of the desert of the sea, etc.", and (Ibid. 30:6) "A prophecy of the beasts of the south in a land of affliction and oppression, lavi and layish (types of lions) among them, efeh and flying serpent, etc." "efeh" is a viper. It was said about this viper, that when it sees the shadow of a bird flying in the air and "links up" with its shadow, its limbs descend, in spite of which (Jeremiah 2:6) "they did not say 'Where is the L–rd who brought us up from the land of Egypt, who led us through the wilderness, a land of deserts and pits, a land of drought and tzalmaveth?'" What is "tzalmaveth"? "tzel" (a shadow) and (i.e., accompanied by) "maveth" (death).
