'Sign' in the Bible

Then some of the scribes and Pharisees said to Him, “Teacher, we want to see a sign from You.”

But He answered them, “An evil and adulterous generation demands a sign, but no sign will be given to it except the sign of the prophet Jonah.

The Pharisees and Sadducees approached, and as a test, asked Him to show them a sign from heaven.

An evil and adulterous generation demands a sign, but no sign will be given to it except the sign of Jonah.” Then He left them and went away.

While He was sitting on the Mount of Olives, the disciples approached Him privately and said, “Tell us, when will these things happen? And what is the sign of Your coming and of the end of the age?”

“Then the sign of the Son of Man will appear in the sky, and then all the peoples of the earth will mourn; and they will see the Son of Man coming on the clouds of heaven with power and great glory.

His betrayer had given them a sign: “The One I kiss, He’s the One; arrest Him!”
