Comentario sobre Exodo 14:25

‎ויסר את אפן מרכבותיו AND HE REMOVED THEIR CHARIOT WHEELS — Through the power of the fire of the pillar of fire the wheels were burnt and the chariots were thus dragged along and those who were sitting in them were thrown about and their limbs were all put out of joint (cf. Mekhilta d'Rabbi Yishmael 14:25).

ויסר את אופן, by means of the column of fire.

ויסר את אופן מרכבותיו, when the Egyptians saw that they were in a state of confusion, they tried to turn around the wheels of their chariots in order to flee; they found themselves unable to do this but all they could do with their utmost efforts was to turn around their chariots with difficulty seeing that those trying to turn around conflicted with those behind them still pressing forward. The reason they did all this was because they had come to the realisation אנוסה מפני ישראל כי ה' נלחם להם , that it was time to flee seeing that G’d Himself was fighting against them on behalf of the Israelites.
