Leviticus 23:37-39

Amplified Bible, Classic Edition

³⁷ These are the set feasts or appointed seasons of the Lord, which you shall proclaim to be holy convocations, to present an offering made by fire to the Lord, a burnt offering and a cereal offering, sacrifices and drink offerings, each on its own day.

³⁸ This is in addition to the Sabbaths of the Lord and besides your gifts and all your vowed offerings and all your freewill offerings which you give to the Lord.

³⁹ Also on the fifteenth day of the seventh month [nearly October], when you have gathered in the fruit of the land, you shall keep the feast of the Lord for seven days, the first day and the eighth day each a Sabbath.
