The nation and land descended from ESAU — the rugged red-sandstone highlands south-east of the Dead Sea, also called SEIR ('hairy,' echoing Esau). The name Edom ('red') is minted from the red stew (25:30) and matches the red Nubian sandstone of the region (whose later capital, Petra, is carved into it). Its whole family tree — Esau's wives and sons, the clan-chiefs (alufim), the older Horite people they displaced, and eight kings who reigned 'before any king reigned over Israel' — fills Genesis 36. Edom and Israel are the archetypal quarreling brothers of the Bible: kin, yet perennial enemies — Edom refuses Israel passage in the wilderness (Numbers 20), and the prophets return to it again and again (Obadiah is entirely an oracle against Edom; Jeremiah 49; Isaiah 34). Herod the Great was an Idumean — a Hellenized Edomite — so the brother-rivalry runs right up to the Gospels.
Approximate. Edom's core is the highland block east of the Arabah, bounded north by the Wadi al-Hasa (the biblical Zered) and running south to the Gulf of Aqaba — the rift and the wadi are real and fixed, the eastern edge simply fades into desert with no line to draw. Later Edomites spread west of the Arabah into the Negev, the region Greeks and Romans called Idumea; that expansion is not shown here.
