The LORD answered their prayer and helped them wipe out the Canaanite army and completely destroy their towns. That's why one of the towns is named Hormah, which means "Destroyed Place."
But when the Amorites in the hill country attacked from their towns, you ran from them as you would run from a swarm of bees. The Amorites chased your troops into Seir as far as Hormah, killing them as they went.
