Charles Ellicott Commentary 2 Kings 8:22

"So Edom revolted from under the hand of Judah unto this day. Then did Libnah revolt at the same time." — 2 Kings 8:22 (ASV)

Yet. —Rather, and (i.e., so).

Until this day. —Down to the time of the composition of the original account from which this summary is extracted. This notice is confirmed by the Assyrian monuments. Esarhaddon and Assurbanipal mention Qa’us-gabrî king of Udumu (Edom), along with Manasseh of Judah, among their tributaries. Esarhaddon also states that his father Sennacherib had reduced “Adumû, a fortified city of Arabia.”

Then Libnah revolted at the same time. —The point of the statement is that the success of Edom encouraged Libnah to throw off the Judean supremacy. For the locality, see Joshua 10:29 and following, Joshua 15:42, and Joshua 21:13. Keil thinks the revolt of Libnah coincided with (it was probably supported by) the Philistine invasion recorded in 2 Chronicles 21:16, and continued until Uzziah reduced the Philistines (2 Chronicles 26:6 and following). From the time of Hezekiah, Libnah again belonged to Judah (2 Kings 19:8; 2 Kings 23:31; 2 Kings 24:18).
