Deuteronomy 28:59-62

59If you refuse to do that, the Lord will punish you and your descendants more and more. You will have lots of pain and many kinds of terrible disease that will not get better.

60He will cause you to have all the same diseases that hurt the Egyptians and that made you very afraid. Those diseases will never leave you alone.

61The Lord will also cause you to have many other terrible diseases. This scroll of God's Law does not say anything about those diseases, but they will destroy you completely.

62At one time, you were as many people as the stars in the sky. But if you do not obey the Lord your God, only a few of you will remain alive.
