And Amaziah strengthened himself, and led forth his people,.... To go to war with the Edomites; not discouraged by the dismission of the hired troops, but trusting in the promise and power of God, he went forth with boldness and intrepidity:
and went to the valley of salt, and smote of the children of Seir, ten thousand; the Edomites; so called, not because they were the posterity of Seir, but because they dwelt in Seir, from whence they drove the descendants of Seir, and dwelt in their stead; see 2 Kings 14:7.
