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.

10229. 'And you shall take the silver of expiations from the children of Israel' means the purifying truths springing from good that are the Church's. This is clear from the meaning of 'the silver' as truth springing from good, dealt with in 1551, 2954, 5658, 6112, 6914, 6917, 8932; from the meaning of 'expiations' as purification from evils, dealt with above in 10218, so that 'the silver of expiations' is truth that purifies; and from the representation of 'the children of Israel' as the Church, dealt with in the places referred to in 9340. The words 'truth that purifies' are used because all purification from evils is effected by means of truths, see 2799, 5954, 7044, 7918, 9089. The implications of all this are that by himself a person thinks nothing but evil; for by himself he does not think about God nor about good and just behaviour towards his neighbour, unless it is to his own advantage. Nor indeed does he think about heaven and eternal life, only about the world and life there. As long as this is a person's state of mind his thought springs from what is below him and not from what is above him, thus from hell and not from heaven. To think what is good therefore a person's thought must spring from heaven, so that his mind must be raised in that direction. This is accomplished solely by means of truths such as exist within the Church, derived from the Word; for those truths teach about the nature of God, who the neighbour is, the existence of heaven, the reality of eternal life, and in particular what evil and good are. When these truths pass into the mind its inner levels are raised above the self, and are accordingly drawn away from those things below the self, thus away from evils. From this it may be recognized that all purification or removal from evils is effected by means of truths, which are therefore called purifying truths.
