What do we learn from "v'Sigzar Omer v'Yakam Lach"?
Divrei Eliyahu: You will decree, and Hashem will fulfill 1 . Malbim - this is because nature will be submissive under you. Yehoshua decreed that the sun stop, and Eliyahu decreed that dew and rain will be only according to his word.
Rashi: "V'Yakam" is like v'Yakum (will be fulfilled).
How will light shine on your ways?
Divrei Eliyahu: Even if you do not decree, via your illuminating ways, light will shine on you automatically - "v'Orach Tzadikim k'Or Nogah Holech va'Or." It constantly gets stronger. Nogah is one who receives light in this world.
Malbim: Until now, your ways were darkness (physical). Now they will be light - elevated above physicality.
