Read Daniel 11 today.

This chapter includes prophecy covering many years and many different empires or kingdoms. Rulers would rise to power, reign for a time, and then fall. It happened over and over again. Some ruled over vast kingdoms, while others ruled small kingdoms. Some ruled for long periods of time, while other for very short periods.
The common denominator is that all were temporary. Over time all trophies tarnish and become covered with dust. Only God remained. Only our relationship with the eternal God will last. God has given you time. Are you using your time to build anything that will endure?
Daniel 11:20 NLT
His successor will send out a tax collector to maintain the royal splendor. But after a very brief reign, he will die, though not from anger or in battle.
