2 Chronicles 20:22-23

New King James Version

²² Now when they began to sing and to praise, ^(A)the Lord set ambushes against the people of Ammon, Moab, and Mount Seir, who had come against Judah; and they were defeated. ²³ For the people of Ammon and Moab stood up against the inhabitants of Mount Seir to utterly kill and destroy them. And when they ^[a]had made an end of the inhabitants of Seir, ^(B)they helped to destroy one another.
