'Thing' in the Bible

Afterwards Jesus found him in the Temple and said to him, "You are now restored to health. Do not sin any more, or a worse thing may befall you."

"This," replied Jesus, "is above all the thing that God requires--that you should be believers in Him whom He has sent."

"Whether he is a sinner or not, I do not know," he replied; "one thing I know--that I was once blind and that now I can see."

From the beginning of the world such a thing was never heard of as that any one should open the eyes of a man blind from his birth.
