That this is what is meant by manna is evident from the words of the Lord Himself in John:

"Our fathers did eat manna in the desert, as it is written, He gave them bread from heaven to eat. The bread of God is he who cometh down from heaven, and giveth life unto the world. I am the bread of life. Your fathers, did eat manna in the desert and are dead. This is that bread which cometh down from heaven, that he that eateth of it may not die. I am the living bread that came down from heaven, if any man eat of this bread he shall live for ever. The bread that I will give is my flesh" (vi. 31-58).

That it is the Lord Himself who is meant by manna and by bread, He plainly teaches, for He says,

"I am the bread of life that came down from heaven."

That it is the Lord as to the Divine Human, He also teaches when He says,

"The bread which I will give is my flesh."

[2] The Lord taught the same when He instituted the holy supper:

"Jesus took bread, and blessed, and gave it to the disciples, and said, Take, eat, this is my body (Matt. xxvi. 26; Mark xiv. 22; Luke xxii. 19).

To eat of this bread is to be conjoined to Him by love, for to eat signifies to appropriate and be conjoined, as said above; and love is spiritual conjunction. The same thing is signified by eating in the kingdom of God, in Luke:

"Blessed is he that eateth bread in the kingdom of God" (xiv. 15).

Again:

"Ye shall eat and drink at my table in the kingdom of God" (xxii. 30).

In Matthew:

"Many shall come from the east and west, and shall recline with Abraham, and Isaac, and Jacob in the kingdom" of God (viii. 11).

(That by Abraham, Isaac, and Jacob, is meant the Lord, may be seen, Arcana Coelestia, n. 1893, 4615, 6098, 6185, 6276, 6804, 6847.) And in John:

"Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man will give unto you" (vi. 27).

[3] (That the Son of man is the Lord as to the Divine Human, may be seen above, n. 63.) The reason why it is called hidden manna is, because the delight of heavenly love, which those 'receive who are conjoined to the Lord by love is quite unknown to those who are not in heavenly love; and this delight no one can receive but he who acknowledges the Divine Human of the Lord; for it proceeds from this. Because this delight was unknown to the sons of Israel in the desert, they therefore called it manna, as is evident in Moses:

"Jehovah said unto Moses, Behold, I will rain bread from heaven for you. And in the morning the dew lay round about the camp. And when the dew that lay was gone up, behold, upon the face of the desert there lay a small round thing; and when they saw it, they said, It is manna (What is this?). Moses said unto them, This is the bread which Jehovah hath given you to eat. And the house of Israel called the name thereof manna" (Exod. xvi. 3 to the end).

"Jehovah fed thee with manna which thou knewest not, neither did thy fathers know; that he might make thee know that man doth not live by bread only, but by every word that proceedeth out of the mouth of Jehovah doth man live" (Deut. viii. 3).

The reason why this delight, which is meant by manna, was unknown to the sons of Israel was, that they were in bodily delight more than other nations; and those who are in this delight cannot know anything at all of heavenly delight. (That the sons of Israel were of such a character may be seen in The Doctrine of the New Jerusalem, n. 248.) It is called delight, and by this is meant the delight of love; for all the delight of life is from love. [4] Because it is the delight of heavenly love that is signified by eating of the hidden manna, it is therefore called the bread of the heavens in David:

"Jehovah commanded the clouds from above, and opened the doors of the heavens; and rained down manna upon them to eat, and gave them of the corn of the heavens" (Psalm lxxviii. 23, 24).

And in another place:

"Jehovah satisfied them with the bread of the heavens (Psalm cv. 40).

It is called the bread of the heavens because it rained down from heaven with the dew, but in the spiritual sense it is called the bread of the heavens because it flows down from the Lord through the angelic heaven; in this sense, no other heaven is meant, and no other bread than that which nourishes the soul of man. That bread is here meant in this sense is evident from the words of the Lord himself in John, where He says, that

He is the manna or bread which came down from heaven (vi. 31-58).

And in Moses, where it is said

that Jehovah fed them with manna that He might teach that man doth not live by bread alone, but by every utterance of the mouth of Jehovah (Deut. viii. 3).

The utterance of the mouth of Jehovah is everything that proceeds from the Lord, and this, specifically, is Divine truth united with Divine good (as may be seen in the work, Heaven and Hell, n. 13, 133, 139, 140, 284-290).

[5] This delight is also described by correspondences in Moses:

The manna was "like coriander seed, white, and the taste of it was like a cake made with honey" (Exod. xvi. 31).

And in another place:

"They made cakes of it; and the taste of it was as of the juice of oil" (Numb. xi. 7, 8).

The reason why the manna had such an appearance and taste was, that the white seed of coriander signifies truth from a celestial origin, a cake the good of celestial love, honey its external delight, oil that love itself, and its juice, whence was the taste, its internal delight, and the rain with the dew, in which the manna was, the influx of Divine truth in which that delight is contained. (That seed signifies truth from a heavenly origin, may be seen, Arcana Coelestia, n. 3038, 3373, 10,248, 10,249: that white is said of that truth, n. 3301, 3993, 4007, 5319; that cake signifies the good of heavenly love, n. 7978, 9992, 9993; that oil signifies that love itself, n. 886, 3728, 9780, 9954, 10,261, 10,269; hence its juice signifies its delight, because the taste is therefrom and the taste is the delight and pleasantness, see n. 3502, 4791-4805. But more may be seen concerning these things in the explanation of chap. xvi. of Exodus in Arcana Coelestia.) The reason why the delight of celestial love is signified by eating of the hidden manna, although by the hidden manna the Lord as to the Divine Human is signified, is that it is the same thing whether we say the Divine Human of the Lord, or the Divine love, for the Lord is Divine love itself, and what proceeds from Him is Divine good united to Divine truth; both belong to love, and are also the Lord in heaven. Therefore to eat of Him is to be conjoined to Him, and this is effected by love from Him. (But these things may be better understood from what is said and own in the work, Heaven and Hell, n. 13-19, 116-125, 126-140; and also in The Doctrine of the New Jerusalem, n. 210-222 and 307.)
