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.

813. That these words mean the point at which the Most Ancient Church finally came to an end, and that 'a hundred and fifty' means that which is both a finishing point and a starting point, cannot be confirmed so easily from the Word as the more simple numbers can which occur frequently. Nevertheless the matter is clear from the number fifteen, dealt with above at verse 20. Fifteen means so few as to be hardly any. This meaning applies all the more to the number 'a hundred and fifty', which is the product of fifteen multiplied by ten, which means remnants. Multiplying fractions, such as a half, a quarter, or a tenth, produces smaller fractions still, till at length there is practically nothing, and then the end or finishing point has been reached. The same number occurs in Chapter 8:3 below where it is said that the waters retreated at the end of a hundred and fifty days. There the meaning is similar. Numbers in the Word have to be understood abstractedly - quite apart from the sense of the letter, for as stated and shown already, they have been included merely to produce the flow of historical events that belongs to the sense of the letter. For example, when seven occurs it means that which is holy - quite abstractedly from periods of time or measurements which it is normally used to quantify. Indeed angels, who perceive the internal sense of the Word, know nothing whatever about periods of time or measurements, let alone what a specific number denotes. Yet they understand the Word completely when it is being read by man. Consequently when a number occurs anywhere at all they cannot possibly have the idea of any numerical value, only of the real thing meant by the number. Likewise in the present context they understand by this number the point at which the Most Ancient Church finally came to an end, and in verse 3 of the next chapter the starting point of the Ancient or new Church.
