are the names of the clans of Esau by their families, by their places, by their names: clan Timnah, clan Alvah, clan Jetheth, clan Aholibamah, clan Elah, clan Pinon, clan Kenaz, clan Teman, clan Mibzar, clan Magdiel, clan Iram. The Hebrew word translated as leader of a clan is aluf, used solely to describe the Dukes of Edom and Moab, in the first five books of Moses. However beginning in the books of the later prophets the word is used to describe Judean generals, for example, in the prophecies of Zachariah twice (9:7, 12:5–6) it had evolved to describe Jewish captains, the word also is used multiple times as a general term for teacher or guide for example in Psalm 55:13. Aluph as it is used to denote teach or guide from the Edomite word for Duke is used 69 times in the Tanakh. If the account may be taken at face value, the kingship of Edom was, at least in early times, not hereditary, perhaps elective. The first book of Chronicles mentions both a king and chieftains. Moses and the Israelite people twice appealed to their common ancestry and asked the king of Edom for passage through his land, along the "King's Highway", on their way to Canaan, but the king refused permission. Accordingly, they detoured around the country because of his show of force or because God ordered them to do so rather than wage war (). The King of Edom did not attack the Israelites, though he prepared to resist aggression. Nothing further is recorded of the Edomites in the Tanakh until their defeat by King Saul of Israel in the late 11th century BC (). Forty years later King David and his general Joab defeated the Edomites in the "Valley of Salt" (probably near the Dead Sea; ; ). An Edomite prince named Hadad escaped and fled to Egypt, and after David's death returned and tried to start a rebellion, but failed and went to Syria (Aramea). From that time Edom remained a vassal of Israel. David placed over the Edomites Israelite governors or prefects, and this form of government seems to have continued under Solomon. When Israel divided into two kingdoms Edom became a dependency of the Kingdom of Judah. In the time of Jehoshaphat (c. 870 – 849 BC) the Tanakh mentions a king of Edom, who was probably an Israelite deputy appointed by
