SEV Biblia, Chapter 20:22
Y cuando comenzaron con clamor y con alabanza, puso el SEÑOR a los hijos de Moab y los del monte de Seir para que asechasen a los hijos de Amón, que venían contra Judá, y se mataron los unos a los otros .
Clarke's Bible Commentary - 2 Chronicles 20:22
Verse 22. The Lord set ambushments] "The WORD of the Lord placed snares among the children of Ammon and Moab; and the inhabitants of the mountain of Gibla, who came to fight with Judah; and they were broken to pieces:" so the Targum. Houbigant translates the place thus: "The Lord set against the children of Ammon and Moab ambushments of those who came from Mount Seir against Judah; and the children of Ammon and Moab were smitten: but they afterwards rose up against the inhabitants of Mount Seir, and utterly destroyed them; who being destroyed, they rose up one against another, and mutually destroyed each other." This is probably the meaning of these verses. Calmet's version is not very different.
John Gill's Bible Commentary
Ver. 22. And when they began to sing and to praise , etc.] They sung more or less all the way they went, from the time they set out, but when they came nearer the enemy, they sung louder and louder: the Lord set ambushments against the children of Ammon, Moab, and Mount Seir, which came against Judah ; some take them to be their own ambushments, which they set for the destruction of Judah; but the Lord turned them against their own confederates, mistaking them for Jews; so the Vulgate Latin version, “the Lord turned their ambushments against themselves;” or rather these were angels, who appeared in the form of the Edomites, and so fell upon the Ammonites and Moabites: and they were smitten ; by them, many of them were destroyed; hence it follows, Ver. 23 . For the children of Ammon and Moab stood up against the inhabitants of Mount Seir , etc.] Supposing that they had acted a treacherous part by them, and took on the side of their enemies: utterly to slay and destroy them ; as they did: and when they had made an end of the inhabitants of Seir ; so that there were none left of them: everyone helped to destroy one another ; in their confusion mistook one another, either for Edomites or Jews, like the Midianites in the times of Gideon.
Matthew Henry Commentary
Verses 20-30 - Jehoshaphat exhorted his troops to firm faith in God. Faith inspires man with true courage; nor will any thing help more to the establishin of the heart in shaking times, than a firm belief of the power, an mercy, and promise of God. In all our trust in the Lord, and ou praises of him, let us especially look at his everlasting mercy to sinners through Jesus Christ. Never was an army so destroyed as that of the enemy. Thus God often makes wicked people destroy one another. An never was a victory celebrated with more solemn thanksgivings.
