Ecclesiastes 5:8

8. From thoughts of the majesty of God the transition is easy to the authority and government alas! so often mis-government! established among men. Solomon well knew that human history has been and would be full of oppression. The tribes of Israel, during the days of the Judges especially, both suffered and inflicted it; and so in the days of his father David. His own royalty was very expensive; his exactions of tribute upon the foreign population in Palestine were severe, (1 Kings 9:20-21,) and even the tribes of Israel after his death declared that his “yoke” was “grievous.” (1 Kings 12:4.)

Marvel not As if evil had no check.

Highest regardeth Divine retribution rules over all. Verified in his own case; for from oppression his own kingdom was finally divided.
