Leviticus 26:37

26:37 They will stumble over each other as those who flee before a sword, though there is no pursuer, and there will be no one to take a stand for you before your enemies.

Joshua 8:20

8:20 When the men of Ai turned around, they saw the smoke from the city ascending into the sky and were so shocked they were unable to flee in any direction. In the meantime the men who were retreating to the desert turned against their pursuers.
