Leviticus 26:19-22
English Standard Version
Chapter 26
19and I will break the pride of your power, and 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 increase, and the trees of the land shall not yield their fruit.
21"Then if you walk contrary to me and will not listen to me, I will continue striking you, sevenfold for your sins.
22And I will let loose the wild beasts against you, which shall bereave you of your children and destroy your livestock and make you few in number, so that your roads shall be deserted.
