Among the Hebrews, were oblations of part of the fruits of the harvest, offered to God as an acknowledgment of his sovereign dominion. There was another sort of first fruits which was paid to God. When bread was kneaded in a family, a portion of it was set apart, and given to the priest or Levite who dwelt in the place. If there were no priest or Levite there, it was cast into the oven, and consumed by the fire. These offerings made a considerable part of the revenues of the priesthood, Leviticus 23:1-44 : Exodus 22:29 . Chron 23: 19. Numb. 15: 19, 20. The first fruits of the Spirit, are such communications of his grace on earth, as fully assure us of the full enjoyment of God in heaven, Romans 8:23 . Christ is called the first fruits of them that slept; for as the first fruits were earnests to the Jews of the succeeding harvest, so Christ is the first fruits of the resurrection, or the earnest of a future resurrection; that as he rose, so shall believers also rise to happiness and life. 1 Corinthians 15:20 . First fruits are mentioned in ancient writers as one part of the church revenue. First fruits, in the church of England, are the profits of every spiritual benefice for the first year, according to the valuation thereof in the king's book.
