'Thing' in the Bible

The first thing Andrew did was to find his brother Simon and say to him, "We have found the Anointed One!" (which is translated "Messiah").

But he responded, "I don't know whether he is a sinner or not. The one thing I do know is that I used to be blind and now I can see!"

The man answered them, "This is an amazing thing! You don't know where he comes from, yet he healed my eyes.

Simon Peter told them, "I'm going fishing." They all told him, "We'll go with you, too." So they went out and got into the boat but didn't catch a thing that night.
