YHVH spoke to Moses, saying:
"Speak to the Children of Israel, saying:
On the fifteenth day of this seventh month
the Festival of Sukkot, seven days for YHVH....
When you have gathered in the yield of the land
celebrate the Festival of YHVH seven days:
a complete rest on the first day
and a complete rest on the eighth day.
On the first day take fruit of lovely trees,
branches of palm trees, boughs of leafy trees
and willows of the brook.
Rejoice in the presence of YHVH your God seven days.
Celebrate it, a festival to YHVH, seven days a year.
An eternal decree throughout the generations:
celebrate it in the seventh month.
Seven days dwell in sukkot;
every citizen in Israel shall dwell in sukkot,
so that your generations may know
that I lodged the Children of Israel in sukkot
when I brought them out of the land of Egypt,
I, YHVH your God. "
(Leviticus 23:33-34, 39-43)
Rabbi El'azar opened
"'Thus says YHVH:
"I remember the devotion of your youth,
your love as a bride
how you followed Me in the wilderness, in a land unsown"'
This verse refers to the Communion of Israel
when She was walking in the wilderness along with Israel.
'I remember the devotion'
This is the cloud of Aaron
