Leviticus 23:37-39

Darby Translation

³⁷ These are the set feasts of Jehovah, which ye shall proclaim as holy convocations, to present an offering by fire to Jehovah, a burnt-offering, and an oblation, a sacrifice, and drink-offerings, everything upon its day;

³⁸ besides the sabbaths of Jehovah, and besides your gifts, and besides all your vows, and besides all your voluntary offerings, which ye give to Jehovah.

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.
