8400. In the fifteenth day of the second month. That this signifies the state relatively, is evident from the signification of the number “fifteen,” from the signification of “day,” and from the signification of “month.” By “month” is signified the end of a former state and the beginning of the following state, thus a new state (see n. 3814); by “day” is signified state in general (n. 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850, 7680); and by “fifteenth” is signified what is new, for by “fourteen days,” or “two weeks,” is signified an entire period, or a state from its beginning to its end (n. 728, 2044, 3845); consequently by “fifteen” is signified what is new, here what is new in life, which is signified by the manna that they received from heaven; for “manna” denotes the good of truth, which is the life of the spiritual man. For the like is signified by “fifteen” as by “eight,” because the eighth day is the first day of the following week. (That “eighth” denotes any beginning, thus what is new as distinguished from what was before, see n. 2044, 2866; and that all numbers in the Word signify things, n. 482, 487, 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495, 4670, 5265, 6175)

813. That this signifies the last limit of the Most Ancient Church, and that “a hundred and fifty” is the last limit, and the first, cannot indeed be so well confirmed from the Word as can the more simple numbers, which are frequently occurring. And yet it is evident from the mention of the number “fifteen” (concerning which above at verse 20), which signifies so few as to be scarcely any; and this is still more the case with the number “a hundred and fifty” composed of fifteen multiplied by ten, which last signifies remains. The multiplication of a few (like the multiplication of a half, a fourth, or a tenth), makes it still less, so that at length it becomes almost none, consequently the end or last limit. The same number occurs in the following chapter (Genesis 8:3), where it is said: “the waters receded at the end of a hundred and fifty days” with the same signification.

[2] The numbers mentioned in the Word are to be understood in a sense entirely abstracted from that of the letter. They are introduced (as has been said and shown before) merely to connect together the historic series that is in the sense of the letter. Thus where “seven” occurs, it signifies what is holy, entirely apart from the times and measures with which the number is commonly joined. For the angels, who perceive the internal sense of the Word, know nothing of time and measure, still less of the number designated; and yet they understand the Word fully, when it is being read by man. When therefore a number anywhere occurs, they can have no idea of any number, but of the thing signified by the number. So here by this number they understand that it denotes the last limit of the Most Ancient Church; and in the following chapter (verse 3), that it denotes the first limit of the Ancient or new Church.
