²² When they began singing and praising, the Lord ^(A)set ambushes against the sons of ^(B)Ammon, Moab, and Mount Seir, who had come against Judah; so they were struck down. ²³ For the sons of Ammon and Moab rose up against the inhabitants of Mount Seir, completely destroying them; and when they had finished with the inhabitants of Seir, ^(C)they helped to destroy one another.
