Deuteronomy 28:59-62

28:59 then the Lord will increase your punishments and those of your descendants – great and long-lasting afflictions and severe, enduring illnesses. 28:60 He will infect you with all the diseases of Egypt that you dreaded, and they will persistently afflict you. 28:61 Moreover, the Lord will bring upon you every kind of sickness and plague not mentioned in this scroll of commandments, until you have perished. 28:62 There will be very few of you left, though at one time you were as numerous as the stars in the sky, because you will have disobeyed the Lord your God.
