Leviticus 26:16-18 New Revised Standard Version (NRSV)
16 I in turn will do this to you: I will bring terror on you; consumption and fever that waste the eyes and cause life to pine away. You shall sow your seed in vain, for your enemies shall eat it. 17 I will set my face against you, and you shall be struck down by your enemies; your foes shall rule over you, and you shall flee though no one pursues you. 18 And if in spite of this you will not obey me, I will continue to punish you sevenfold for your sins.
