Arcana Coelestia #5295
5295. 'And let them store up grain' means at the same time every good of truth. This is clear from the meaning of 'storing up' as collecting at the same time and preserving; and from the meaning of 'grain' as natural good, dealt with in 3580, in this case the good of truth present in the natural. For the good of truth is truth present in will and action. The reason 'grain' means good is that in the spiritual sense 'the field' is the Church, and therefore everything connected with the field - such as seed, sower, harvest, standing crop, grain, and also the head or tip of the grain, besides specifically wheat, barley, and much else - describes something to do with the Church. And everything to do with the Church has a connection with goodness and truth.
Hosea 2:8-9
8
For she did not know that I gave her the grain, the new wine, and the oil, and multiplied to her silver and gold, which they used for Baal.
9
Therefore I will take back my grain in its time, and my new wine in its season, and will pluck away my wool and my flax which should have covered her nakedness.
