Parallel
2 Chronicles 20:22
Brenton's English Septuagint · Berean Standard Bible
And when they began the praise and thanksgiving, the Lord caused the children of Ammon to fight against Moab, and [the inhabitants of] mount Seir that came out against Juda; and they were routed.
The moment they began their shouts and praises, the LORD set ambushes against the men of Ammon, Moab, and Mount Seir who had come against Judah, and they were defeated.
