The words "fields" and "ripe for harvest" are metaphors. The "fields" represent the non-Jewish people or Gentiles. The words "ripe for harvest" mean that the Gentiles are ready to receive the message of Jesus, just as fields are ready to be harvested. AT: "look up and see these non-Jewish people! They are ready to accept my message, just like crops in the fields are ready for people to harvest them" (See: [[rc://en/ta/man/translate/figs-metaphor]])
# He who is harvesting receives wages and gathers fruit for everlasting life
