Leviticus 26:23-25

‘And if by these things you do not learn your lesson regarding Me, but you show hostility toward Me, then I in turn will show hostility toward you; and I, even I, will strike you seven times for your sins. I will also bring upon you a sword which will execute vengeance for the covenant; and when you gather together into your cities, I will send a plague among you, so that you will be handed over to the enemy.
