Sforno on Exodus 15:10/ספורנו על שמות ט״ו:י׳

1נשפת ברוחך, You used the very same wind You had used to dry out the sea bed after splitting it to now turn against the pursuers and to turned into overwhelming and turbulent waters.

2אדירים, not a reference to the waters but to the men who had been considered mighty, invincible, etc. [I suppose the unusual exegesis is based on the dividing tone sign tipcha under the word במים, which indicates that it belongs to the preceding words. Ed.] The people to whom Moses refers are the ones who had been described in 14,7 as שלישים על כולו.
