Edom

Edom, ancient land bordering ancient Israel, in what is now southwestern Jordan, between the Dead Sea and the Gulf of Aqaba. The Edomites probably occupied the area about the 13th century bce. Though closely related to the Israelites (according to the Bible, they were descendants of Esau), they had frequent conflicts with them and were probably subject to them at the time of the Israelite kingdom (11th–10th century bce). Edom prospered because of its strategic location on the trade route between Arabia and the Mediterranean and its copper industry at Ezion-geber. Edom and Moab were later conquered by the Nabataeans, and the Edomites migrated to southern Judaea, where they were known in New Testament times as Idumaeans.
