Leviticus 26:12-16

I will walk among you and be your God, and you shall be My people. I am the LORD your God, who brought you out of the land of Egypt, that you should not be their slaves; I have broken the bands of your yoke and made you walk upright. ‘But if you do not obey Me, and do not observe all these commandments, and if you despise My statutes, or if your soul abhors My judgments, so that you do not perform all My commandments, but break My covenant, I also will do this to you: I will even appoint terror over you, wasting disease and fever which shall consume the eyes and cause sorrow of heart. And you shall sow your seed in vain, for your enemies shall eat it.
