Leviticus 23:36-38

Amplified Bible

³⁶ For seven days you shall present an offering by fire to the Lord. On the eighth day you shall have a holy convocation and present an offering by fire to the Lord. It is a festive assembly; you shall not do any laborious work [on that day].

³⁷ ‘These are the appointed times (established feasts) of the Lord, which you shall proclaim to be holy convocations, to present an offering by fire to the Lord, a burnt offering and a grain offering, sacrifices and drink offerings, each on its own day. ³⁸ This is in addition to the [weekly] Sabbaths of the Lord, and in addition to your gifts and all your vowed offerings and all your freewill offerings, which you give to the Lord.
