Leviticus 26:18-21

18‘And after all this, if you do not obey Me, then I will punish you seven times more for your sins.

19I will break the pride of your power; I will make your heavens like iron and your earth like bronze.

20And your strength shall be spent in vain; for your land shall not yield its produce, nor shall the trees of the land yield their fruit.

21‘Then, if you walk contrary to Me, and are not willing to obey Me, I will bring on you seven times more plagues, according to your sins.
