And Amaziah strengthened himself, and led forth his people, and went to the valley of salt, and smote of the children of {h} Seir ten thousand.

(h) For the Idumeans whom David had brought to subjection rebelled under Jehoram Jehoshaphat's son.

Jamieson-Fausset-Brown Bible Commentary

11. valley of salt-This ravine lies to the south of the Dead Sea. The arms of Amaziah, in reward for his obedience to the divine will, were crowned with victory-ten thousand of the Edomites were slain on the field, and as many taken prisoners, who were put to death by precipitation "from the top of the rock" [2Ch 25:12]. This rock might be situated in the neighborhood of the battlefield, but more probably it formed one of the high craggy cliffs of Selah (Petra), the capital of the Edomites, whither Amaziah marched directly from the Valley of Salt, and which he captured (2Ki 14:7). The savage cruelty dealt out to them was either in retaliation for similar barbarities inflicted on the Hebrews, or to strike terror into so rebellious a people for the future. The mode of execution, by dashing against stones (Ps 137:9), was common among many ancient nations.

Matthew Henry's Concise Commentary

25:1-13 Amaziah was no enemy to religion, but cool and indifferent friend. Many do what is good, but not with a perfect heart. Rashness makes work for repentance. But Amaziah's obedience to the command of God was to his honour. A firm belief of God's all-sufficiency to bear us out in our duty, and to make up all the loss and damage was sustain in his service, will make his yoke very easy, and his burden very light. When we are called to part with any thing for God and our religion, it should satisfy us, that God is able to give us much more than this. Convinced sinners, who have not true faith, always object to self-denying obedience. They are like Amaziah; they say, But what shall we do for the hundred talents? What shall we do if by keeping the sabbath holy we lose so many good customers? What shall we do without this gain? What shall we do if we lose the friendship of the world? Many endeavour to quiet their consciences by the pretence that forbidden practices are necessary. The answer is, as here, The Lord is able to give thee much more than this. He makes up, even in this world, for all that is given up for his sake.
