Amos 8:9-10

9The Lord God says, ‘At that time, I will make the sun go down at noon. I will make the earth become dark in the daytime.

10Your parties will become funerals. You will not sing happy songs but you will weep. You will wear rough clothes and you will cut off all your hair. You will be as sad as if your only son had died. That will be a very bad day for you.’
