'In that Day' in the Bible

And my anger shall be kindled against them in that day, and I will forsake them, and I will hide my face from them, and they shall be devoured, and many evils and troubles shall befall them, and they will say in that day, Have not these evils befallen me because my God is not in my midst?

And I will entirely hide my face in that day for all the evils that they have wrought, because they turned unto other gods.
