kings that reigned in the land of Edom
It is characteristic of Scripture that the kings of Edom should be enumerated before the kings of Israel. The principle is stated in 1 Corinthians 15:46 .

Adam--Christ; Cain--Abel; Cain's posterity--Seth's posterity; Saul--David; Israel--the true Church, etc.
