David is dying and the maneuvering to replace him has started. Sometimes people hate politics (the maneuvering for power) and it’s true that people usually don’t love one another in the process, but it is also true that we need good leaders and wise men in power. If you have a desire for it, submit that to God. If you don’t, remember to trust God. Ultimately Jesus will take the throne, instead of Solomon.
Therefore, some lessons : appeal to current authority, let God advance you, deal justly with those under your care.
