'Sign' in the Bible

Then the Jewish leaders asked him, "What sign can you show us as authority for doing these things?"

Now this was the second sign that Jesus did after coming from Judea to Galilee.

When the people saw the sign that he had done, they kept saying, "Truly this is the Prophet who was to come into the world!"

So they asked him, "What sign are you going to do so that we may see it and believe in you? What actions are you performing?

Many people came to him and kept saying, "John never performed a sign, but everything that John said about this man is true!"

The crowd was going out to meet Jesus because they had heard that he had performed this sign.
