preparations for war with Edom, which had revolted under Joram of Judah, 2Ki 8:22; upon the victory over the Edomites in the Valley of Salt, and on the results of this war; - on all which we have in 2Ki 14:7 only this short note: “he smote Edom in the valley of Salt 10,000 men, and took Selah in war, and called its name Joktheel unto this day.” But the more exact statements of the Chronicle as to the preparations and the results of this war and victory are important for Amaziah's later war with Kings Joash of Israel, which is narrated in 2Ch 25:17. of our chapter, because in them lie the causes of that war, so fatal to Amaziah; so that the history of Amaziah is essentially supplemented by those statements of the Chronicle which are not found in 2 Kings.
Verses 5-7
2Ch 25:5-7The preparations for the war against Edom, and the victory over the Edomites in the Valley of Salt. - 2Ch 25:5. Amaziah assembled Judah, i.e., the men in his kingdom capable of bearing arms, and set them up (ordered them) according to the princes of thousands and hundreds, of all Judah and Benjamin, and passed them in review, i.e., caused a census to be taken of the men liable to military service from twenty years old and upward. They found 300,000 warriors “bearing spear and target” (cf. 2Ch 14:7); a relatively small number, not merely in comparison with the numbers under Jehoshaphat, 2Ch 17:14., which are manifestly too large, but also with the numberings made by other kings, e.g., Asa, 2Ch 14:7. By Joram's unfortunate wars, 2Ch 21:17, those of Ahaziah, and especially by the defeat which Joash sustained from the Syrians, 2Ch 24:23, the number of men in Judah fit for war may have been very much reduced. Amaziah accordingly sought to strengthen his army against the Edomites, according to 2Ch 25:6, by having an auxiliary corps of 100,000 men from Israel (of the ten tribes) for 100 talents of silver, i.e., he took them into his pay. But a prophet advised him not to take the Israelitish host with him, because Jahve was not with Israel, viz., on account of their defection from Jahve by the introduction of the calf-worship. To Israel there is added, (with) all the sons of Ephraim, to guard against any misunderstanding.
Verse 8
Amaziah is to go alone, and show himself valiant in war, and the Lord will help him to conquer. This is without doubt the thought in 2Ch 25:8, which, however, does not seem to be contained in the traditional Masoretic text. האל יכשׁילך can hardly, after the preceding imperatives - do, be strong for battle - be otherwise
