Babylon was merciless in the way they plundered smaller nations and forced them to pay exorbitant amounts of tribute. This was wrongful gain. But they would reap what they had sown. The proud and arrogant Babylon was conquered by the Medes and the Persians about seventy years after this prophecy was written. Babylon trusted in idols that they had made.
Idols are lifeless and they delude people.
In contrast to all idols, God is living and all-powerful. He is completely sovereign, so let all the earth keep silent before Him. Let's obey this command, and stop complaining about God's timing in dealing with sin. Let's stop doubting God's sovereignty over all things. Let's stop questioning His ways.
