“We [Jeremiah and Obadiah] have heard a rumour [confidential information] from the LORD.” God originated this information, and He let certain individuals know what He intended to do. Then the trusted individuals, such as Obadiah, transmitted the information to the public. Such confidential information should make us bestir ourselves to righteousness.
The Book of Obadiah is fourth in the listing of the 12 minor prophets. Generally speaking, the listing is in chronological order with the exception of Obadiah, which stands out like a sore thumb as not fitting the sequence. Although no specific king’s reign is mentioned to pinpoint the time setting and Obadiah’s relationship to the chronology of the kings, internal evidence in the book helps us to know when Obadiah gave his message, as will be seen.
We think the reason Ezra, who superintended the compilers of the Old Testament, inserted Obadiah after Amos, rather than much further on, is that this book concerns only Edom (or Esau) from beginning to end. Moreover, it seems to be a sequel to the prophecy of Amos, part of which pertains to Edom, and provides more details with regard to that message of rebuke.
