1 Chronicles 1:43–51
These are the kings who reigned in the land of Edom before any king reigned over the Israelites: Bela son of Beor. His city was named Dinhabah. / When Bela died, Jobab son of Zerah from Bozrah reigned in his place. / When Jobab died, Husham from the land of the Temanites reigned in his place.
