2 Chronicles 20:22-24

New Revised Standard Version Catholic Edition

²² As they began to sing and praise, the Lord set an ambush against the Ammonites, Moab, and Mount Seir, who had come against Judah, so that they were routed. ²³ For the Ammonites and Moab attacked the inhabitants of Mount Seir, destroying them utterly; and when they had made an end of the inhabitants of Seir, they all helped to destroy one another.

²⁴ When Judah came to the watchtower of the wilderness, they looked toward the multitude; they were corpses lying on the ground; no one had escaped.
