Jubilees 7:36

For three years the fruit of everything that is eaten will not be gathered: and in the fourth year its fruit will be accounted holy [and they will offer the first-fruits], acceptable before the Most High God, who created heaven and earth and all things. Let them offer in abundance the first of the wine and oil (as) first-fruits on the altar of the Lord, who receives it, and what is left let the servants of the house of the Lord eat before the altar which receives (it).
