Leviticus 26:19-22
19. I will break the pride of your power; I will make your heavens like iron and your earth like bronze.
20. And 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.
22. I will also send wild beasts among you, which shall rob you of your children, destroy your livestock, and make you few in number;and your highways shall be desolate.
