664. And after three days and a half.- That this signifies when completed, thus the end of the old church, and the beginning of a new church, is evident from the signification of three days and a half, as denoting fulness or completion at the end of the old church, when there is the beginning of a new church, concerning which see above (n. 658). The reason why it is said, after three days and a half, is, that days, in the Word, signify states, here, the last state of the church. For all times, in the Word, as hours, days, weeks, months, years, and ages, signify states in the Word, as in this case, the last state of the church, when there is no longer any good of love or truth of faith remaining. Because days signify states, and since in the first chapter of Genesis the establishment of the Most Ancient Church is treated of which was accomplished successively from one state to another, therefore it is said there that there was evening and there was morning the first, the second, the third, the fourth, the fifth, and sixth days, unto the seventh, when it was completed (Genesis 1:5, 8, 13, 19, 23, 31), and the days there do not mean days, but the successive states of the regeneration of men at that time, and the consequent establishment of the church with them. So also elsewhere in the Word.

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.
