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.

8515. 'Because Jehovah has given you the sabbath' means the joining together of goodness and truth by the Lord. This is clear from the meaning of 'the sabbath' as the joining together of goodness and truth, dealt with in 8495. The truth that it is brought about by the Lord is meant by the words 'Jehovah has given', for in the Word 'Jehovah' is the Lord.
