Leviticus 23:39-41

Darby Translation

³⁹ But on the fifteenth day of the seventh month, when ye have gathered in the produce of the land, ye shall celebrate the feast of Jehovah seven days: on the first day there shall be rest, and on the eighth day there shall be rest.

⁴⁰ And ye shall take on the first day the fruit of beautiful trees, palm branches and the boughs of leafy trees, and willows of the brook; and ye shall rejoice before Jehovah your God seven days.

⁴¹ And ye shall celebrate it as a feast to Jehovah seven days in the year: [it is] an everlasting statute throughout your generations; in the seventh month shall ye celebrate it.
