Vayikra 23:38-40

Orthodox Jewish Bible

³⁸ Beside the Shabbatot of Hashem, and beside your mattenot, and beside all your nederim, and beside all your nedavot (freewill offerings), which ye give unto Hashem.

³⁹ Also in the fifteenth day of the seventh month, when ye have gathered in the crop of HaAretz, ye shall keep a Chag (Feast) unto Hashem shivat yamim; on the first day shall be a Shabbaton, and on the eighth day shall be a Shabbaton.

⁴⁰ And ye shall take you on the Yom HaRishon the fruit of the citron tree, branches of temarim (date palms), and twigs of plaited trees, and willows of the brook; and ye shall rejoice before Hashem Eloheichem shivat yamim.
