2 Kings 8:22

Yet[R.V. so] Edom revolted The conjunction is changed to conform to the rendering in 2 Chronicles 21. As the army of Joram was defeated, the Edomites secured their independence, and that continued till the date of the record from which the compiler of the Kings drew his information. So he copies faithfully -unto this day".

Then Libnah revolted R.V. did Libnah revolt. The change is in conformity with Chronicles, because of the similarity of the Hebrew. Libnah was situate in the lowland between the mountains of Judah and the Mediterranean coast. It was a strong city with a king when the Israelites took it under Joshua (Joshua 10:29-39). It is mentioned afterwards (2 Kings 19:8) as besieged by Sennacherib. The narrative of the Chronicler adds as the reason of the revolt -because he [Joram] had forsaken the Lord the God of his fathers". The revolt of Libnah does not seem to be connected in any way with that of Edom. The time was opportune and both Edomites and Libnites availed themselves of it.
