Halakhah for Numbers 14:14

"for I caused Israel to dwell in Sukkot" (Leviticus 23:43) --these were clouds of glory according to Rabbi Eliezer, Rabbi Akiva says 'these were actual sukkot.' (Sukkah 11b). According to the position of Rabbi Eliezer, it is obvious that we would want to remember such a tremendous feat as being surrounded by the clouds of glory...for inside the clouds of glory God was revealed to all the people, as it says, "You, O LORD, appear in plain sight when Your cloud rests over them and when You go before them in a pillar of cloud by day and in a pillar of fire by night."(Numbers 14:14) However, for Rabbi Akiva whose understands these to be physical sukkot, what is so great about these that the Torah instructs us to build them "in order that future generations may know that I made the Israelite people live in booths"? (Leviticus 23:43)
