Leviticus 23:37-39 Christian Standard Bible (CSB)
37 “These are the Lord’s appointed times that you are to proclaim as sacred assemblies for presenting fire offerings to the Lord, burnt offerings and grain offerings, sacrifices and drink offerings, each on its designated day. 38 These are in addition to the offerings for the Lord’s Sabbaths, your gifts, all your vow offerings, and all your freewill offerings that you give to the Lord.
39 “You are to celebrate the Lord’s festival on the fifteenth day of the seventh month for seven days after you have gathered the produce of the land. There will be complete rest on the first day and complete rest on the eighth day.
