2850. And as the sand which is upon the sea shore. That this signifies the multitude of corresponding memory-knowledges, is evident from the signification of the “sea,” as being memory-knowledges in general, or a gathering of them (see n. 28, 2120); and from the signification of “sand,” as being memory-knowledges specifically or in particular. Memory-knowledges are compared to “sand,” because the little stones of which sand is made, in the internal sense signify memory-knowledges (n. 643, 1298). It is here said that they shall be multiplied “as the stars of the heavens,” and also “as the sand of the sea shore,” because the stars or knowledges have relation to the rational, but the sand of the sea shore or memory-knowledges to the natural. When the things of the rational man, namely, the goods and truths of knowledges, agree with those of the natural man, namely, with memory-knowledges, so that they make a one, or mutually confirm each other, they then correspond. To this correspondence the Lord reduces the rational and natural things of man when he regenerates him, or makes him spiritual. From this cause it is that both the stars of the heavens and the sand of the sea shore are here mentioned; otherwise one would have been sufficient.
