Leviticus 23:37-39

New Revised Standard Version Catholic Edition

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.
