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.

Ezekiel 27:24

These were your traffickers in choice wares, in wrappings of blue and embroidered work, and in chests of rich clothing, bound with cords and made of cedar, among your merchandise.
