Leviticus 23:39-40

New International Version

³⁹ “‘So beginning with the fifteenth day of the seventh month, after you have gathered the crops of the land, celebrate the festival^(A) to the Lord for seven days;^(B) the first day is a day of sabbath rest, and the eighth day also is a day of sabbath rest. ⁴⁰ On the first day you are to take branches^(C) from luxuriant trees—from palms, willows and other leafy trees^(D)—and rejoice^(E) before the Lord your God for seven days.
