Achbor in the Bible Encyclopedia - ISBE

ak'-bor (`akhbor, "mouse"): (1) The father of Baal-hanan, who was the seventh of the eight kings who reigned in Edom before there were kings in Israel (Gen 36:38,39; 1 Ch 1:49). (2) The son of Micaiah (called in Chronicles Abdon the son of Micah) who went with Hilkiah the priest and other high officials, at the command of King Josiah, to consult Huldah the prophetess concerning the book that had been found (2 Ki 22:12,14; 2 Ch 34:20). It may be presumed that this Achbor is also the man mentioned in Jer (26:22; 36:12) as the father of Elnathan, who went to Egypt for King Jehoiakim in order to procure the extradition of Uriah the prophet, and who protested against the burning of Baruch's roll.
