The vision of Ovadiah...behold I have made you small among the nations. The only way for us to understand prior events that our eyes didn't see is through the retellings of trustworthy men that we can rely on and from the philosophical proofs. And here the pesukim do not explain who Ovadiah was and in what generation he lived in, but Chazal have a mesorah from generations that he was the Ovadiah that was mentioned in Sefer Melachim, in the days of Achav who served Achav's household and that he was an Edomite convert descended from Elifaz (the character found in the parable of Job). The Midrash Tanchuma says about Ovadiah's vision, Hashem said to Elifaz, you rebuked my servant Job in a vision saying "In thought filled visions of the night..." (Job 4:13). I will bring from you a prophet that will exact punishment on your father's house (presumably Edom?) in a vision. And in Sanhedrin 39:2, Rabbi Yitzchak says, Hashem said, Ovadiah lived between two wicked people and did not learn from their ways- Achav and Jezebel. He was descended from Esau the wicked who lived among the righteous Yitzchak and Rivka and did not learn from their ways. Efraim Miksha (R' Meir's student) said in the name of R' Meir that Ovadiah was a Edomite convert and therefore he prophesized of the downfall of his ancestral nation, as it says "from within the forest comes the materials to make the axe to chop down the forest...and...a thigh rots from within..." and I already wrote in the introduction in the initial investigation why this book comes after Hosea, Yoel and Amos if Ovadiah proceeded them chronologically.
