Then Solomon went to Ezion Geber and to Elat on the coast in the land of Edom.

During Jehoram’s ¹  reign Edom freed themselves from Judah’s control and set up their own king. ² 

Jehoram crossed over to Zair with his officers and all his chariots. The Edomites, who had surrounded him, attacked at night and defeated him and his chariot officers. ¹ 

You defeated Edom ¹  and it has gone to your head. ²  Gloat over your success, ³  but stay in your palace. Why bring calamity on yourself? Why bring down yourself and Judah along with you?” ⁴ 

But Amaziah did not heed the warning, ¹  for God wanted to hand them over to Joash because they followed the gods of Edom. ² 

So Edom has remained free from Judah’s control to this very day. ¹  At that same time Libnah also rebelled and freed themselves from Judah’s control ²  because Jehoram ³  rejected the Lord God of his ancestors.
