Leviticus 23:37-39

New Catholic Bible

³⁷ These are the feasts of the Lord on which you shall proclaim holy assemblies, making a burnt offering to the Lord, and offering up a cereal offering, a sacrifice, and a drink offering, each on its own day, ³⁸ in addition to the Sabbaths of the Lord, your gifts, your vows, and all of the free-will offerings that you give to the Lord. ³⁹ On the fifteenth day of the seventh month, when you have gathered in the fruit of the land, you shall celebrate a feast to the Lord for seven days. On the first day there will be a Sabbath rest, and on the eighth day there will be a Sabbath rest.
