Leviticus 26:16; Leviticus 26:36

16 then I will do this to you: I will bring on you sudden terror, wasting diseases and fever that will destroy your sight and sap your strength. You will plant seed in vain, because your enemies will eat it.

36 “ ‘As for those of you who are left, I will make their hearts so fearful in the lands of their enemies that the sound of a windblown leaf will put them to flight. They will run as though fleeing from the sword, and they will fall, even though no one is pursuing them.
