Which Succot did the Jews use?

Hi,

"Initially the Torah wrote בסכת ("in huts"), and later it wrote בסוכת (also "in huts", but spelled differently) to show that they lived in two types of Succot - (1) The Succot of the clouds of glory, and (2) the actual Succot when they lay siege to the cities in the war of Sichon and Og."

(Rabbi Avraham Danzig, Chayyei Adam 146)

Good moed,
Mordechai
