Leviticus 26:20-22

American Standard Version

²⁰ and your strength shall be spent in vain; for your land shall not yield its increase, neither shall the trees of the land yield their fruit.

²¹ And if ye walk contrary unto me, and will not hearken unto me, I will bring seven times more plagues upon you according to your sins. ²² And I will send the beast of the field among you, which shall rob you of your children, and destroy your cattle, and make you few in number; and your ways shall become desolate.
