To whom will Pharaoh say "Nevuchim Hem ba'Aretz"?
What does "Nevuchim Hem ba'Aretz" mean?
Rashi: They are locked in (entangled) 1 (and do not know how to escape).
Rashbam: It is the acronym of 'Nivchei Yam' - implying that the hidden depths of the sea prevented them from fleeing forwards. 2
About whom Pharaoh will say "Sagar Aleihem ha'Midbar" (that he/it enclosed Yisrael)?
Seforno and Targum Yonasan: He will say that Ba'al Tzefon had locked them in the desert (and they could not escape).
Rashbam and Targum Onkelos: He will say that the desert had enclosed them. 1
They were unable to flee back (the way they had come), due to the snakes, serpents, scorpions and wild beasts that abound in the desert (Rashbam).
