What do Pesukim 14-16 add to the previous Pasuk?
Rashi (citing Tanchuma) Rashbam, Seforno and Targum Yonasan: When the Egyptians will see the extent of Hashem's Hashgachah Ke'lalis (communal Providence) over K'lal Yisrael, 1 and how He then suddenly killed the entire nation in the desert, they will attribute it to the might of the local inhabitants, which rendered them more than a match for Hashem, Kevayachol. 2
Ramban: When the Egyptians will see the extent of Hashem's Hashgachah Ke'lalis (communal Providence) over K'lal Yisrael, 3 and how He then suddenly killed the entire nation in the desert, they will attribute it to the fact that, although Hashem was able to overpower the Egyptian gods, He was unable to defeat the gods of the Cana'anim.
Rashbam: How He led them lovingly with a Pillar of Cloud and a Pillar of Fire.
Rashi: Because Par'oh was not comparable to the thirty-one kings of Cana'an. The Ramban objects to this explanation however, bearing in mind that Hashem killes the Egyptian firstborn and drowned their entire army in one fell-swoop - so why would He not be able to do the same with the Cana'anim, irrespective of their superior strength?
