'Sign' in the Bible

So then the Jewish leaders responded, "What sign can you show us, since you are doing these things?"

Jesus did this as his second miraculous sign when he returned from Judea to Galilee.

Now when the people saw the miraculous sign that Jesus performed, they began to say to one another, "This is certainly the Prophet who is to come into the world."

So they said to him, "Then what miraculous sign will you perform, so that we may see it and believe you? What will you do?

Many came to him and began to say, "John performed no miraculous sign, but everything John said about this man was true!"

Because they had heard that Jesus had performed this miraculous sign, the crowd went out to meet him.
