Leviticus 26:23-25

23And if in spite of these things you do not accept My discipline, but continue to walk in hostility toward Me, 24then I will act with hostility toward you, and I will strike you sevenfold for your sins. 25And I will bring a sword against you to execute the vengeance of the covenant. Though you withdraw into your cities, I will send a plague among you, and you will be delivered into the hand of the enemy.
