Leviticus 26:18

14 If, however, you fail to obey Me and to carry out all these commandments,

15 and if you reject My statutes, despise My ordinances, and neglect to carry out all My commandments, and so break My covenant,

16 then this is what I will do to you: I will bring upon you sudden terror, wasting disease, and fever that will destroy your sight and drain your life. You will sow your seed in vain, because your enemies will eat it.

17 And I will set My face against you, so that you will be defeated by your enemies. Those who hate you will rule over you, and you will flee when no one pursues you.

18 And if after all this you will not obey Me, I will proceed to punish you sevenfold for your sins.

19 I will break down your stubborn pride and make your sky like iron and your land like bronze,

20 and your strength will be spent in vain. For your land will not yield its produce, and the trees of the land will not bear their fruit.

21 If you walk in hostility toward Me and refuse to obey Me, I will multiply your plagues seven times, according to your sins.

22 I will send wild animals against you to rob you of your children, destroy your livestock, and reduce your numbers, until your roads lie desolate.
