Jewish holidays: Harvest festival or Historic celebration?

Hi,

"Each [Jewish] festival takes place at the time of the year when Gd reveals Himself in Nature's evolution, in the same way as the deed that forms the basis of the festival reveals Gd at work in the sphere of human history."

(R' Samson Raphael Hirsch, Horeb, Chapter 23)

Have a great day,

Mordechai
