Leviticus 26:23-25

23‘1And if by these things you do not learn your lesson regarding Me, but you show hostility toward Me,

24then I in turn will 2show hostility toward you; and I, even I, will strike you 3seven times for your sins.

25I will also bring upon you a sword which will execute 4vengeance for the covenant; and when you gather together into your cities, I will send a 5plague among you, so that you will be handed over to the enemy.
