Leviticus 26:16
26:16 I for my part will do this to you: I will inflict horror on you, consumption and fever, which diminish eyesight and drain away the vitality of life. You will sow your seed in vain because your enemies will eat it.
Leviticus 26:20
26:20 Your strength will be used up in vain, your land will not give its yield, and the trees of the land will not produce their fruit.
