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.

Deuteronomy 20:19-20
19
When you shall besiege a city a long time, in making war against it to take it, you shall not destroy its trees by wielding an axe against them; for you may eat of them, and you shall not cut them down; for is the tree of the field man, that it should be besieged of you?
20
Only the trees of which you know that they are not trees for food, you shall destroy and cut them down; and you shall build bulwarks against the city that makes war with you, until it fall.
