This is clear from the meaning of 'water' as cognitions and facts, which are the truths of the natural, dealt with in 28, 2702, 3058; from the meaning of 'troughs' or water-holders, which, since they are containers of water, in the internal sense mean the goods that go with truth, for these goods are the holders of truth, dealt with in 3095- and from the meaning of 'coming to drink' as the affection for truth. The reason why 'coming to drink' means the affection for truth is that it implies thirst, and 'thirst' in the Word means appetite and desire, and so the affection for knowing and taking in truth. It has this meaning because 'water' means truth in general. 'Hunger' however means appetite and desire, and so the affection for assimilating good. It does so because 'bread', which is used to denote food in general, 2165, means good. From this it is evident that these words mean affections for truth.
