5212. And behold seven ears of corn came up upon one stalk. That this signifies memory-knowledges of the natural joined together, is evident from the signification of "ears," or spikes, of corn, as being memory-knowledges belonging to the natural (of which in what follows); and from the signification of "upon one stalk," as being joined together; for in respect to their origin things on one stalk are joined together. The reason why "ears" or spikes of corn signify memory-knowledges, is that "corn" signifies the good of the natural (see n. 3580), because memory-knowledges are the containants of the good of the natural, as the ears are of the corn; for in general all truths are vessels of good, and so also are memory-knowledges, for these are lowest truths.
Lowest truths, or truths of the exterior natural, are called memory-knowledges, because they are in man's natural or external memory, and because they partake for the most part of the light of the world, and hence can be presented and represented to others by forms of words, or by ideas formed into words by means of such things as are of the world and its light. The things in the inner memory, however, insofar as they partake of the light of heaven, are not called memory-knowledges, but truths; nor can they be understood except by means of this light, or expressed except by forms of words, or ideas formed into words, by means of such things as are of heaven and its light. The memory-knowledges here signified by "ears," or spikes, are memory-knowledges of the church, in regard to which see above (n. 4749, 4844, 4964, 4965).
[2] The reason why there were two dreams, one of the seven kine and the other of the seven ears of corn, is that in the internal sense both naturals, the interior and the exterior, are treated of, and in what follows, the rebirth of both. By the "seven kine" are signified the things of the interior natural called truths of the natural (see n. 5198); and by the "seven ears of corn," the truths of the exterior natural called memory-knowledges.
[3] Interior and exterior memory-knowledges are signified by "ears of the river Euphrates even to the river of Egypt," in Isaiah:
It shall be in that day that Jehovah will shake off from the ear of the river even unto the river of Egypt, and ye shall be gathered one to another, ye sons of Israel. And it shall be in that day that a great trumpet shall be sounded, and they shall come that are perishing in the land of Assyria, and the outcasts in the land of Egypt; and they shall bow themselves to Jehovah in the mountain of holiness at Jerusalem (Isa. 27:12-13);
"the perishing in the land of Assyria" denote interior truths, and the "outcasts in the land of Egypt," exterior truths or memory-knowledges.
[4] So also in Mark the comparison with the blade, the ear, and the corn, involves the rebirth of man by means of memory-knowledges, truths of faith, and goods of charity:
Jesus said, So is the kingdom of God, as when a man casteth seed upon the earth; then sleepeth and riseth night and day, but the seed germinates and grows while he knoweth not. For the earth beareth fruit of itself; first the blade, then the ear, after that the corn in the ear. But when the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come (Mark 4:26-29);
the "kingdom of God," which is compared to the blade, the ear, and the corn, is heaven in man through regeneration; for one who has been regenerated has the kingdom of God within him, and becomes in image the kingdom of God or heaven. The "blade" is the first memory-knowledge; the "ear" is the memory-knowledge of truth thence derived; the "corn" is the derivative good. Moreover, the laws enacted in regard to gleanings (Lev. 19:9; 23:22), and in regard to the liberty of plucking the ears from the standing corn of the neighbor (Deut. 23:25), and also in regard to eating no bread, nor parched corn, nor green ears, until the offering of God was brought (Lev. 23:14), represented such things as are signified by "ears."
