Matthew 12:36-40

But I tell you that for every careless word that people speak, they will give an account of it on the day of judgment.

For by your words you will be justified, and by your words you will be condemned.” The Desire for Signs

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

But He answered and said to them, “An evil and adulterous generation craves a sign; and so no sign will be given to it except the sign of Jonah the prophet;

for just as Jonah was in the stomach of the sea monster for three days and three nights, so will the Son of Man be in the heart of the earth for three days and three nights.
