Mambo Ya Walawi 23:39

“ ‘Basi kuanzia siku ya kumi na tano ya mwezi wa saba, baada ya kuvuna mazao yote ya nchi, mtaadhimisha sikukuu kwa Bwana kwa siku saba; siku ya kwanza ni mapumziko, pia siku ya nane ni mapumziko.

Also in the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast unto the LORD seven days: on the first day shall be a sabbath, and on the eighth day shall be a sabbath.
