Leviticus 26:12-16

I will also 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 erect. ‘But if you do not obey Me and do not carry out all these commandments, if, instead, you reject My statutes, and if your soul abhors My ordinances so as not to carry out all My commandments, and so break My covenant, I, in turn, will do this to you: I will appoint over you a sudden terror, consumption and fever that will waste away the eyes and cause the soul to pine away; also, you will sow your seed uselessly, for your enemies will eat it up.
