Daniel 6:2 (ESV)

2 and over them three high officials, of whom Daniel was one, to whom these satraps should give account, so that the king might suffer no loss.

Darius also appoints three people who are to supervise those 120 satraps. These officials, acting as administrators or ministers of the realm, have a very important place in the kingdom. They are very powerful men. They can report to the king and make sure that the satraps under them are not acting too independently and pursuing their own ends. The surprising thing is that Daniel is one of these three high officials. Daniel had been in the service of the Babylonians for a very long time. Yet the Medes and Persians immediately appoint him to their service. They give him a very high position in the management of the Empire. Here you see that it is the Lord who is King! He rules. It is necessary that, at the end of the seventy years of exile, there is a person at the court who can use his high position to bring about the end of the exile for God’s people.  

The Lord ensured that the Medes and Persians did not put Daniel to death, even though he was third in the Babylonian Empire. He takes care that Daniel, at his advanced age, is given a high position in the new kingdom. Darius even wants to give Daniel a higher position. Behind this we can again see God’s rule over all.
