6:1-2 When the Medo-Persian alliance overthrew the Neo-Babylonian Empire, it acquired much geographic territory that it proceeded to incorporate into its kingdom. The Persian Empire became the largest that the world had yet seen eventually encompassing modern Turkey, Egypt, and parts of India and North Africa as well as Babylonia. Darius divided his realm into 120 satrapies or provinces and set a satrap ("protector of the realm") in charge of each one (cf. Esth. 1:1; 8:9).211They reported to three commissioners one of whom was Daniel. Evidently Darius had heard about Daniel's unique gifts and accomplishments as a Babylonian administrator and wanted to use him in his cabinet.
6:3 As time passed, Daniel distinguished himself above the other commissioners, even though he was in his 80s. Darius purposed to put him in charge of them all, to elevate him to prime minister.
These verses set the stage for what follows by helping the reader appreciate how Darius felt about Daniel.
