1 Chronicles 1:42-44

42 The sons of Etzer: Bilhan, Zaavan, Jaakan. The sons of Dishan: Uz and Aran.

43 Now these were the kings who ruled in the land of Edom, before any king ruled over Bnei-Yisrael: Bela the son of Beor, the name of his city was Dinhabah.

44 When Bela died, Jobab the son of Zerah of Bozrah ruled in his place.
