Leviticus 23:37-39

New Revised Standard Version, Anglicised

³⁷ These are the appointed festivals of the Lord, which you shall celebrate as times of holy convocation, for presenting to the Lord offerings by fire—burnt-offerings and grain-offerings, sacrifices and drink-offerings, each on its proper day— ³⁸ apart from the sabbaths of the Lord, and apart from your gifts, and apart from all your votive offerings, and apart from all your freewill-offerings, which you give to the Lord.

³⁹ Now, the fifteenth day of the seventh month, when you have gathered in the produce of the land, you shall keep the festival of the Lord, lasting seven days; a complete rest on the first day, and a complete rest on the eighth day.
