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 so that you would not be their slaves; and I broke the bars of your yoke and made you walk upright [with heads held high as free men]. ‘But if you do not obey Me and do not [obediently] do all these commandments, if, instead, you reject My statutes, and if your soul rejects My ordinances, so that you will not [obediently] do all My commandments, and in this way break My covenant, I, in turn, will do this to you: I will appoint over you sudden terror, consumption, and fever that will waste away the eyes and cause the soul to languish also. And you will sow your seed uselessly, for your enemies will eat what you plant.
