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.

It is bound to seem strange and very far-fetched to everybody that these details have this meaning, that is to say, that the numbers three hundred, fifty, and thirty mean remnants, and in particular that they were few; also that 'length, breadth, and height' means holiness, truth, and good. But in addition to what has been stated and shown above about numbers at verse 3 of this chapter, where a hundred and twenty means the remnants of faith, this matter may also become clear to anybody from the fact that people who possess the internal sense, as good spirits and angels do, are beyond anything earthly, bodily, or purely worldly, and so beyond anything involving numbers and measurements. Yet the Lord enables them to perceive the Word fully, and to do so quite independently from such concepts. This being so, it becomes quite clear that numbers and measurements embody celestial and spiritual things. The latter however are so remote from the sense of the letter that such things cannot possibly be seen. This applies to every single celestial or spiritual thing. From this also anyone may recognize how insane it is to desire to inquire into matters of faith through sensory evidence and factual knowledge and to refuse to believe unless one grasps them by that method.
