258. In the Word there is a spiritual sense, which is called the internal sense.

No one can know what the internal sense of the Word is, unless he knows what correspondence is (n. 2895, 4322). The whole and every part, even to the most minute, of the natural world, corresponds to spiritual things, and thence is significative of them (n. 1886-1889, 2987-3003, 3213-3227). The spiritual things to which natural things correspond assume another appearance in the natural, so that they are not distinguished (n. 1887, 2395, 8920). Scarcely anyone knows at this day, where, or in what part is the Divine of the Word, when nevertheless it is in its internal or spiritual sense, which at this day is not known (n. 2899, 4989). The mystic things of the Word are nothing else than what its internal or spiritual sense contains, which treats of the Lord, of His kingdom, and of the church, and not of the natural things which are in the world (n. 4923). The prophetic parts of the Word are in many places unintelligible, and therefore of no use without the internal sense; illustrated by examples (n. 2608, 8020, 8398). As what is signified by "the white horse," mentioned in Revelation (n. 2760[1-2].). By "the keys of the kingdom of the heavens" that were given to Peter, see the Preface to the 22 nd (Arcana Coelestia 9410) chapter of Genesis (n. 9410). By "the flesh," "blood," "bread," and "wine," in the Holy Supper, and thus why it was instituted by the Lord (n. 8682). By the prophecies of Jacob concerning his sons in the 49th chapter of Genesis (n. 6306, 6333-6465). By many prophecies concerning Judah and Israel, which by no means tally with that people, nor in the literal sense have any coincidence with their history (n. 6333, 6361, 6415, 6438, 6444). Besides innumerable other instances (n. 2608).

Of the spiritual or internal sense of the Word in a summary (n. 1767-1777, 1869-1879). There is an internal sense in the whole and in every particular part of the Word (n. 1143, 1984, 2135, 2333, 2395, 2495, 2619). Such things do not appear in the sense of the letter, but nevertheless they are contained within it (n. 4442).

8682. 'To eat bread with the father-in-law of Moses before God' means making their own these things coming from Divine Good. This is clear from the meaning of 'eating' as making one's own, dealt with in 3168, 3513 (end), 3596, 3832, 4745; and from the meaning of 'bread' as the good of love, dealt with in 2165, 2177, 3464, 3735, 4211, 4217, 4735, 5915, its coming from Divine Good being meant by the statement that they were going to eat bread 'before God'. Here 'bread' is used to mean all the food they had then, in particular the flesh of the sacrifices; for when sacrifices were offered, the flesh in them was eaten beside the altar. For the meaning of 'bread' as all food in general, see 2165.

The reason why the flesh of the sacrifices was eaten was in order that making heavenly good one's own might be represented, as well as togetherness in love. The flesh of a sacrifice, eaten by them then, meant the good of love, which was why this was for them a sacred feast. For the meaning of 'flesh' as the good of love, see 7850. From this one can see what the Lord meant when He said that they were to eat His flesh, John 6:53-56, and also, when He instituted the Holy Supper, that the bread was His body, Matthew 26:26. No one can possibly know what He meant then unless he knows that His words have an inner sense, and that in this sense celestial and spiritual realities are meant instead of natural things, and that natural things correspond to those realities and have spiritual meanings in keeping with correspondences. Without knowledge of these things no one could ever know why the Holy Supper was instituted, what is holy about the bread, why the bread is the body and is the flesh, and countless other questions besides these.
