Midst
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.

Arcana Coelestia#7201
7201. 'Therefore say to the children of Israel' means that the law of God will enable those who belong to the Lord's spiritual kingdom to discern. This is clear from the representation of Moses, the one who is told to 'say to the children of Israel', as the law of God, dealt with in 6723, 6752; from the meaning of 'saying' as discerning, dealt with in 1791, 1815, 1819, 1822, 1898, 1919, 2080, 2506, 2515, 2619, as enabling to discern, since the command 'say' has reference to the law of God; and from the representation of 'the children of Israel' as those who belong to the Lord's spiritual kingdom, dealt with in 6426, 6677.
