Reply To: Beshalach – Tefila

In the introduction to part of tefila, Oz Yashir, it says originally חומה, wall with a vov and then חמה without a vov, anger. The GRA explains that originally it also says בתוך הים ביבשה referring to Nachshon ben Aminodov who jumped into the water before it dried out, so it says with a vov, wall, whereas later it says ביבשה בתוך הים, for the rest of the Jews where they went into the dry water in the sea, saying it without a vov meaning anger.
