671. 'Pairs of all you shall cause to enter the ark to keep them alive means the regeneration of these. This becomes clear from what has been stated in the previous verse, to the effect that truths cannot be regenerated except by means of goods and delights. Nor therefore can things of faith be regenerated except through those of charity. Hence the statement here about pairs of all having to enter, clearly meaning that both truths, which belong to the understanding, and goods, which belong to the will, were to do so. With someone who has not yet been regenerated an understanding of truth and a will for good do not exist but merely appear to do so, and are referred to as such in everyday speech. It is possible for rational truths and for facts to exist with that person, but these have no life. It is also possible for goods which merely look like those of the will, such as those present with gentiles or even with animals, to exist there. But these have no life either; they are merely semblances. With man such things are in no sense alive until he has been regenerated and they have in this way been made alive by the Lord. In the next life what has life and what does not is perceived very distinctly. Truth that has no life is perceived instantly as something material, all tangled and closed up, while good that has no life is perceived as something wooden, bony, and stone-like. But truth or good made alive by the Lord is open, living, and full of what is spiritual and celestial - open even from the Lord Himself. This applies to every idea and action, even to the smallest of either of them. This is why the statement is here made about pairs having to enter the ark to keep them alive.

7284. 'And Moses was a son of eighty years' means the state and essential nature of the law from God. This is clear from the representation of 'Moses' as the law from God, dealt with in 6771, 6827; and from the meaning of 'eighty years as the state and essential nature of the law from God, that is to say, among those who belonged to the spiritual Church, at the first time of visitation. What is meant specifically by 'eighty' cannot be stated because it entails the entire state and nature of the law from God among them at that time. 'Eighty' can mean a state of temptations, see 1963, and when it does so it entails the same meaning as forty. But because it is also the product of ten multiplied by eight, the meaning of eighty must be sought from these numbers as well. For what is meant by ten, see 576, 1906, 1988, 2284, 3107, 4638; and for what is meant by eight, 2044, 2866. In general all numbers serve to mean spiritual realities, and more particularly the states and essential nature of those realities, see 482, 487, 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495, 4670, 5265, 5191, 5335, 5708, 6175.
