'Sign' in the Bible

The Jews then said to Him, “What sign do You show us as your authority for doing these things?”

This is again a second sign that Jesus performed when He had come out of Judea into Galilee.

Therefore when the people saw the sign which He had performed, they said, “This is truly the Prophet who is to come into the world.”

So they said to Him, “What then do You do for a sign, so that we may see, and believe You? What work do You perform?

Many came to Him and were saying, “While John performed no sign, yet everything John said about this man was true.”

For this reason also the people went and met Him, because they heard that He had performed this sign.
