Genesis 36 repeatedly identifies Esau with Edom; Obadiah addresses Edom as the nation growing from that ancestral line. The Jacob–Esau family history therefore becomes the background for the later Israel–Edom prophetic conflict.

Deuteronomy calls Esau’s descendants Israel’s brethren and assigns them Seir; Obadiah addresses that same Edomite people in their mountain homeland, so the Torah supplies both kinship and geographic background.

Obadiah 1–4 and Jeremiah 49:14–16 share the summons against Edom, pride-of-heart language, rocky/high dwelling imagery, and the promise that God will bring Edom down.

Obadiah’s judgment against proud Edom provides a strong prophetic backdrop for Malachi’s declaration that Edom’s mountains have been laid waste and that rebuilding will not overturn God’s verdict.
