1 Kings 1 is all about succession of the throne. 1 Kings 2 is all about security for the throne. How will the man of God's own choosing-Solomon-become the man God establishes- How will the kingdom of God, which only comes by grace, be established and last forever---To answer that, the writer -perhaps Jeremiah- records David's final words being the first duty of the new King, Solomon. David's words to his son are driven by a concern of, and for, two truths of God's covenant- that God's covenant promises are generational, and those covenant promises are guaranteed.
