6538. 'Which is at the crossing of the Jordan' means which is one of introduction into cognitions of good and truth. This is clear from the meaning of 'the Jordan' as introduction into cognitions of good and truth, thus the first sector of the Lord's kingdom and the Church as one goes in, and the last as one comes out, dealt with in 4255. The rivers where the land of Canaan came to an end were representative of the outermost things within the Lord's kingdom, see 1585, 4116, 4240. This is why 'the crossing of the Jordan' means introduction into cognitions of good and truth, for cognitions of good and truth are what come first and serve to introduce a person into the things that constitute the Church.

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.
