9. In the Word there is a spiritual sense, which is called the internal sense. No one can know what the spiritual or internal sense of the Word is, unless he knows what correspondence is (n. 2895, 4322). Each and all things, even the most minute, which are in the natural world, correspond to spiritual things, and thence signify them (n. 2890-2893, 2897-3003, 3213-3227). The spiritual things to which natural things correspond, as assume another appearance in the natural, so that they are not recognized (n. 1887, 2396, 8920). Scarcely anyone knows wherein resides the Divine of the Word, when nevertheless it is in its internal and spiritual sense, which at this day is not known even to exist (n. 2980, 4989). The mystical contents of the Word are no other than those of its internal or spiritual sense, which treats of the Lord, of the glorification of His Human, of His kingdom, and of the church, and not of the natural things which are in the world (n. 4923). The prophetic writings are in many places unintelligible, and therefore of no use, without the internal sense, illustrated by examples (n. 2608, 8020, 8398). As for instance, with respect to what is signified by "the white horse" in Revelation (n. 2760 seq.). What by "the keys of the kingdom of the heavens," that were given to Peter, see the preface to Genesis 22, and n. 9410. What by "flesh," "blood," "bread," and "wine," in the Holy Supper (n. 8682). What by the prophecies of Jacob concerning his sons (Gen. 49; n. 6306, 6333-6465). What by many prophecies concerning Judah and Israel, which by no means tally with that nation, nor in the sense of the letter have any coincidence with their history (n. 6331, 6361, 6415, 6438, 6444). Besides many other instances (n. 2608). More may be seen of the nature of correspondence in the work on Heaven and Hell (n. 87-115 and 303-310). Of the internal or spiritual sense of the Word in a summary (n. 1767-1777, 1869-1879). In each and all things of the Word there is an internal sense (n. 1143, 1984, 2135, 2333, 2395, 2495, 2619). Such things do not appear in the sense of the letter, but nevertheless they are within it (n. 4442).
