Obadiah 1:7
All the men of thy confederacy have brought thee even to the border: the men that were at peace with thee have deceived thee, and prevailed against thee; they that eat thy bread have laid a wound under thee: there is none understanding in him.
Obadiah's prophecy belongs to the time of Jacob's trouble. In that prophecy Jacob represents believers and Esau represents unbelievers. This symbolism applies to the final conflict with the image beast just before Christ's return.
