7522. 'And there will then be dust in all the land of Egypt' means the damnation of those falsities in the natural mind. This is clear from the meaning of 'dust' as that which is damned, dealt with above in 7418; from the meaning of 'the ashes of the furnace', which were turned into dust, as falsities that are the product of evil desires, dealt with just above in 7519, 7520; and from the meaning of 'the land of Egypt' as the natural mind, dealt with in 5276, 5278, 5280, 5288, 5301. The meaning of 'dust' as that which is damned is evident from the places in the Word quoted in 7418, and also from the following in Moses,

If you will not obey the voice of Jehovah your God, cursed shall you be in the city, cursed shall you be in the field. Jehovah will make the rain of your land dust and grit; ² it will come down onto you from heaven until you are destroyed. Deuteronomy 28:15-16, 24.

5278. 'And all the abundance of corn in the land of Egypt will be thrust into oblivion' means the removal of truth and the seeming deprivation of it in both parts of the natural. This is clear from the meaning of forgetting or 'being thrust into oblivion' as a removal and the seeming deprivation that results from this; from the meaning of 'the abundance of corn' as the multiplication of truth, that is, truth that has been multiplied, dealt with just above in 5276; and from the meaning of 'the land of Egypt' as the natural mind or a person's natural, both parts of it in this case, as just above in 5276.

[2] The reason forgetting or 'being thrust into oblivion' means a removal and seeming deprivation is that something akin to this happens to the memory and to thought that relies on it. The actual matters that a person is thinking about are immediately beneath his attention, while related matters spread out in order around them, extending to unrelated ones furthest away, which at that time are in oblivion. Matters of a contrary nature are separated from these, hanging downwards and revealing themselves underneath, where they serve to counterbalance what is above them. This ordered arrangement is effected by means of good flowing in. Such is the way in which the whole of a person's thought is ordered. The truth of this can be seen from people's thoughts in the next life. There in the light of heaven it is quite normal for people's thoughts to be presented sometimes in a visual manner, at which times the form in which those thoughts are arranged is demonstrated. From this it may be seen that 'forgetting' in the internal sense means nothing else than a removal and seeming deprivation.
