Leviticus 26:14-17

14If, however, you fail to obey Me and to carry out all these commandments, 15and if you reject My statutes, despise My ordinances, and neglect to carry out all My commandments, and so break My covenant, 16then 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. 17And 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.
