Leviticus 26:37

And brother shall disregard brother as in war, when none pursues; and ye shall not be able to withstand your enemies.

And they shall fall one upon another, as it were before a sword, when none pursueth: and ye shall have no power to stand before your enemies.

They will stumble over one another, as it were before the sword, when no one pursues. You will have no power to stand before your enemies.
