9437. 'And Moses was in the mountain forty days and forty nights' means the instructions given and influx in their completeness. This is clear from the meaning of 'forty' as completeness. 'Forty' means completeness because 'four' means that which is complete, 9103, as similarly does 'ten', 3107, 4638, and forty is the product of four multiplied by ten. For compound numbers have a meaning similar to the simple numbers of which they are the product, 5291, 5335, 5708, 7973; and all numbers in the Word mean spiritual realities, see 575, 3252, 4264, 4495, 4670, 5265, 6175. All this goes to explain why Moses was in the mountain forty days and forty nights. The fact that 'forty' here means the instructions given and the influx in their completeness is evident from Chapters 25-32 which come next, recording the instructions Moses received, that is, instructions regarding the ark, Aaron, the urim and thummim, and sacrifices. The reason why influx in its completeness is also meant is that at that time Moses began to represent the outward holiness of the Word, which acted as the intermediary between the Lord and the people, and mediation is accomplished by means of influx through that holiness into the representative existing among that people, 9419.

[2] It was because 'forty' represented completeness that Moses remained on Mount Sinai forty days and forty nights not only this time but also on another occasion, Exodus 34:28; Deuteronomy 9:18, 25; 10:10. For the same reason the children of Israel wandered in the wilderness forty years until, as it says in Numbers 14:33-34; 32:13, all that generation had been consumed; Jonah told the Ninevites that their city would be overturned after forty days, Jonah 3:4; the prophet was commanded to lie on his right side and bear the iniquity of the house of Judah forty days, Ezekiel 4:6; it says regarding Egypt that it would be made completely desolate for forty years, after which they would be gathered from the peoples, Ezekiel 29:11-13; and the earth was rained on forty days and forty nights, so that it was inundated with the flood, Genesis 7:4, 12, 17. From all this it is evident why the wicked person was to receive forty blows, Deuteronomy 25:3, for 'forty blows' meant the punishment in its completeness. It is also evident what should be understood in the prophecy of Deborah and Barak when it says that no shield or spear was seen among the forty thousand of Israel, Judges 5:8, 'among the forty thousand of Israel' meaning among them all. It is in addition evident why the temple built by Solomon was forty cubits long, 1 Kings 6:17, as was the new temple, according to Ezekiel 41:2; for in the highest sense 'the temple' means the Lord, and in the internal sense heaven and the Church, so that 'forty' means completeness in respect of representation. And it has a like meaning in other places.

3108. These two verses deal with the introduction of truth into good. But the nature of this introduction does not fit easily into the pattern of thought of anyone whose mind is illumined solely by such things as are seen in the light of the world, and not at the same time by those seen in the light of heaven, by which those belonging to the light of the world are illumined. People who are devoid of good and consequently of faith have no other ideas in their minds than those formed from objects seen in the light of the world. They do not know what the spiritual is, nor even what the rational is in the genuine sense, but only the natural, to which they ascribe everything. Here also is the reason why those things stated in the internal sense about the introduction of truth into good appear to them too remote to mean anything at all. Yet to those who see in the light of heaven they are considered most precious.

[2] With regard to the introduction of truth into good, before truth has been introduced and rightly joined it does indeed reside with man, yet it has not so to speak become his or his own. But as soon as it is introduced into its own good it does become his own. It goes out of his external memory and passes over into the internal memory. Or what amounts to the same, it ceases to exist in the natural or external man, and passes over into the rational or internal man, where it clothes itself with the person himself and constitutes his humanity, that is, his own human character. This is the situation with all truth that is being joined to its good, as also in a similar way with falsity that is being joined to evil which it calls good. The difference however is that truth opens the rational and so makes a person rational, whereas falsity closes the rational and makes him irrational, though he seems to himself while in the darkness enveloping him at this time to be more rational than others.
