The "midst" of something in the Bible represents the thing that is most central and most important to the spiritual state being described, the motivation that drives everything else. In general this will be something we love or feel, because at the core of things we are what we love; our loves define us.

(参考: Apocalypse Revealed 44, 90, 268; Arcana Coelestia 2252, 2940, 10153, 10365, 10557, 10635, 10641)

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.
