7 Amaziah roundly defeated Edom in the Valley of Salt to the tune of ten thousand dead. In another battle he took The Rock and renamed it Joktheel, the name it still bears.

Matthew Henry's Commentary on 2 Kings 14:7

Commentary on 2 Kings 14:1-7

(Read 2 Kings 14:1-7)

Amaziah began well, but did not go on so. It is not enough to do that which our pious predecessors did, merely to keep up the common usage, but we must do it as they did, from the same principle of faith and devotion, and with the same sincerity and resolution.
