Arcana Coelestia # 3068
3068. 'Let down now your pitcher' means submitting facts. This becomes clear from the meaning of 'letting down' as submitting, and from the meaning of 'a pitcher' as facts. The reason why a water-pot or a pitcher means facts is that 'water' means truth, 680, 739, 2702, and a pitcher is a vessel with water in it, even as factual knowledge is a vessel with truth in it. All factual knowledge is a vessel for truth, and all truth is a vessel for good. Factual knowledge without truth is an empty vessel, and so is truth without good; but factual knowledge in which truth is held is a vessel that is filled, as is truth in which good is held. Affection which is an attribute of love is what joins them together so that they may exist in order. For love is spiritual conjunction.

1163. 'Cush, Mizraim, Put, and Canaan' were just so many nations who in the internal sense mean cognitions, knowledge, and the forms of ritual which belong to faith separated from charity. This becomes clear from the Word where these nations are mentioned in various places, for these nations mean such things in those places. That is to say, 'Cush' or Ethiopia means interior cognitions of the Word by which people confirm false assumptions. 'Mizraim' or Egypt means knowledge, or the various facts by which they wish to probe into the arcana of faith and in so doing confirm assumptions that are false. 'Put' or Libya means cognitions drawn from the literal sense of the Word by means of which in a similar way they confirm false assumptions. 'Canaan' or the Canaanites means forms of ritual or external worship that are separated from internal. Since all of these have been separated from charity they are called 'the sons of Ham'. The same nations also mean simply cognitions and knowledge, 'Cush' meaning interior cognitions of the Word, 'Egypt' knowledge, 'Put' cognitions obtained from the literal sense of the Word. This is the reason they are used in both senses, bad as well as good, as becomes clear from the places quoted below.
