Arcana Coelestia # 6777
6777. 'And filled the troughs' means that from there they enriched teachings about charity. This is clear from the meaning of 'filling from the well' as enriching from there, that is, from the Word; and from the meaning of 'the trough' as teachings about charity. The reason why 'the trough' or water-holder means teachings about charity is that it is a runnel made of wood into which water from a well is drawn to water flocks; for in the internal sense that which is made of wood means the good of charity, 3720,'drawing' means gaining instruction, 3058, 3071, 'the water' that is drawn means the truth of faith, 2702, 3058, 4976, 5668, 'the well' from which it is drawn means the Word, 2702, 3424, 6774, and 'watering flocks' means giving instruction in good from the Word, 3772. All this shows that 'the trough' is the teaching about charity.
Arcana Coelestia # 1110
1110. People who have assumed that righteousness and merit lay in their good works and so have attributed the power of achieving salvation to themselves, not to the Lord and to His righteousness and merit, and who in thought and life have confirmed themselves in this idea, have their assumptions converted in the next life into delusions in which they seem to themselves to be cutting wood. This is exactly how it appears to them. I have spoken to them. When they are doing their work and are asked whether they are not tired out, they reply that they have not yet done enough work to be able to merit heaven. While they are cutting pieces of wood it seems as though something of the Lord is underneath the wood, so that the wood appears as merit. And the more something of the Lord seems to be in the pieces of wood the longer they remain in that condition. But when this delusion starts to fade they are getting nearer the end of vastation. At length they become such that they too are able to be admitted into good communities, though they still waver for a long time between truth and falsity. Because they have led a conscientious life the Lord takes great care of them, and is sending angels to them time and again. These are the people who in the Jewish Church were represented by 'hewers of wood', Joshua 9:23, 27.
