'Retreat' in the Bible

The messenger said to David, "The men overpowered us and attacked us in the field. But we forced them to retreat all the way to the door of the city gate.

But the soldiers replied, "You should not do this! For if we should have to make a rapid retreat, they won't be too concerned about us. Even if half of us should die, they won't be too concerned about us. But you are like ten thousand of us! So it is better if you remain in the city for support."

You make my enemies retreat; I destroy those who hate me.
