'Sign' in the Bible

Then the Jews retorted, “What sign (attesting miracle) can You show us as [proof of] your authority for doing these things?”

This is the second sign (attesting miracle) that Jesus performed [in Cana] after He had come from Judea to Galilee [revealing that He is the Messiah].

When the people saw the sign (attesting miracle) that He had done, they began saying, “This is without a doubt the promised Prophet who is to come into the world!”

So they said to Him, “What sign (attesting miracle) will You do that we may see it and believe You? What [supernatural] work will You do [as proof]?

Many came to Him, and they were saying, “John did not perform a single sign (attesting miracle), but everything John said about this Man was true and accurate.”

For this reason the crowd went to meet Him, because they heard that He had performed this [miraculous] sign.
