Leviticus 26:14–16

14 “But if you do not obey me and observe all these commands—15 if you reject my statutes and despise my ordinances, and do not observe all my commands—and break my covenant, 16 then I will do this to you: I will bring terrorm on you—wasting disease and fever that will cause your eyes to fail and your life to ebb away. You will sow your seed in vain because your enemies will eat it.
