Leviticus 26:17; Leviticus 26:36

17 I will set my face against you, and you shall be struck down before your enemies. Those who hate you shall rule over you, and you shall flee when none pursues you.

36 And as for those of you who are left, I will send faintness into their hearts in the lands of their enemies. The sound of a driven leaf shall put them to flight, and they shall flee as one flees from the sword, and they shall fall when none pursues.
