Others, trying to test Jesus, demanded that he show them a miraculous sign from heaven to prove his authority.
As the crowd pressed in on Jesus, he said, “This evil generation keeps asking me to show them a miraculous sign. But the only sign I will give them is the sign of Jonah.
They answered, “Show us a miraculous sign if you want us to believe in you. What can you do?
They were trying to trap him into saying something they could use against him, but Jesus stooped down and wrote in the dust with his finger.
It is foolish to the Jews, who ask for signs from heaven. And it is foolish to the Greeks, who seek human wisdom.
