Leviticus 26:23-25
23 “‘If in spite of these things you do not accept my correction but continue to be hostile toward me,
24 I myself will be hostile toward you and will afflict you for your sins seven times over.
25 And I will bring the sword upon you to avenge the breaking of the covenant. When you withdraw into your cities, I will send a plague among you, and you will be given into enemy hands.
