Leviticus 23:37-39

21st Century King James Version

³⁷ “‘These are the feasts of the Lord which ye shall proclaim to be holy convocations, to offer an offering made by fire unto the Lord, a burnt offering and a meat offering, a sacrifice and drink offerings, every thing upon his day”

³⁸ besides the Sabbaths of the Lord, and besides your gifts, and besides all your vows, and besides all your freewill offerings which ye give unto the Lord.

³⁹ “‘Also on the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast unto the Lord seven days; on the first day shall be a sabbath, and on the eighth day shall be a sabbath.
