8400. 'On the fifteenth day of the second month' means this state considered in relation ... This is clear from the meaning of the number 'fifteen', from the meaning of 'day', and from the meaning of 'month'. 'Month' means the end of the previous state and the beginning of the next, thus a new state, 3814; 'day' means a state in general, 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850, 7680, and 'the fifteenth' means that which is new. For 'fourteen days' or two weeks mean a whole period or state from the beginning to the end of it, 728, 2044, 3845; 'fifteen' therefore means something new, in this instance newness of life, meant by the manna which they received from heaven, 'manna' being the good of truth, which is the life of a spiritual person. Fifteen is similar in meaning to eight, because the eighth day is the first day of a following week. For the meaning of 'the eighth day' as any beginning whatever, thus something new that is distinct and separate from what has gone before, see 2044, 2866; and for the fact that all numbers in the Word have spiritual realities as their meaning, 482, 487, 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495, 4670, 5265, 6175.

2044. That 'a son eight days old' means any beginning whatever to purification is clear from the meaning of 'the eighth day'. 'A week', which consists of seven days, means the entire period of any state and length of time - of reformation, regeneration, or temptation, either of the individual in particular or of the Church in general. So the expression 'week' is used whether the period is one of a thousand years, or of a hundred, or of ten, or else one of days, hours, or minutes, and so on, as may become clear from the places quoted in Volume One, in 728. And because the eighth day is the first day of the following week it here means any new beginning whatever. From this it is also clear that just as circumcision itself was a representative of purification, so also was the time when it took place, namely the eighth day. Not that the uncircumcised on that day entered a purer state and on that account were made pure. Rather even as 'circumcision' was a sign meaning purification, so 'the eighth day' meant that such purification ought to go on all the time and so always to be taking place as if from a new beginning.
