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.

Isaiah 58:11-12
11
and Yahweh will guide you continually, and satisfy your soul in dry places, and make strong your bones; and you shall be like a watered garden, and like a spring of water, whose waters don't fail.
12
Those who shall be of you shall build the old waste places; you shall raise up the foundations of many generations; and you shall be called The repairer of the breach, The restorer of paths to dwell in.
