Joshua 8:15, 24

And Joshua and all Israel made as if they were beaten before them, and fled by the way of the wilderness.

And it came to pass, when Israel had made an end of slaying all the inhabitants of Ai in the field, in the wilderness wherein they pursued them, and they were all fallen by the edge of the sword, until they were consumed, that all Israel returned unto Ai, and smote it with the edge of the sword.
