21:10 So the Edomites revolted from under the hand of Judah unto this day. The same time [also] did {e} Libnah revolt from under his hand; because he had forsaken the LORD God of his fathers.
(e) Read 2Ki 8:22.
21:10 Libnah - Libnah seems to have set up for a free state. And the reason is here given, both why God permitted it, and why they did it, because Jehoram was become an idolater. While he adhered to God, they adhered to him; but when he cast God off, they cast him off. Whether this would justify them in their revolt or no, it justified God's providence which suffered it.
21:1-11 Jehoram hated his brethren, and slew them, for the same reason that Cain hated Abel, and slew him, because their piety condemned his impiety. In the mystery of Providence such men sometimes prosper for a time; but the Lord has righteous purposes in permitting such events, part of which may now be made out, and the rest will be seen hereafter.
