Genesis 36:31

’ואלה המלכים וגו AND THESE ARE THE KINGS etc. — There were eight and Jacob raised an equal number in whose days the kingdom of Esau temporarily ceased to exist, viz., Saul, Ishbosheth, David, Solomon, Rehoboam, Asa, Abiah and Jehoshaphat. For of the days of Yoram his (Jehoshaphat’s) son it is written, (2 Kings 8:20) “In his days Edom revolted from under the hand of Judah and made a king over themselves”, whereas in the days of Jehoshaphat it is written, (1 Kings 22:48) “And there was no king in Edom: a deputy was king”.

וְאֵ֙לֶּה֙ הַמְּלָכִ֔ים אֲשֶׁ֥ר מָלְכ֖וּ בְּאֶ֣רֶץ אֱד֑וֹם לִפְנֵ֥י מְלׇךְ־מֶ֖לֶךְ לִבְנֵ֥י יִשְׂרָאֵֽל׃

And these are the kings that reigned in the land of Edom, before there reigned any king over the children of Yisra᾽el.
