Leviticus 23:37-39

Good News Translation

(³⁷ These are the religious festivals on which you honor the Lord by gathering together for worship and presenting food offerings, burnt offerings, grain offerings, sacrifices, and wine offerings, as required day by day. ³⁸ These festivals are in addition to the regular Sabbaths, and these offerings are in addition to your regular gifts, your offerings as fulfillment of vows, and your freewill offerings that you give to the Lord.)

³⁹ When you have harvested your fields, celebrate this festival for seven days, beginning on the fifteenth day of the seventh month. The first day shall be a special day of rest.
