Matthew 12:37

³⁵The good man out of his good treasure brings out good things, and the evil man out of his evil treasure brings out evil things.

³⁶I tell you that every idle word that men speak, they will give account of it in the day of judgment.

³⁷For by your words you will be justified, and by your words you will be condemned.”

³⁸Then certain of the scribes and Pharisees answered, “Teacher, we want to see a sign from you.”

³⁹But he answered them, “An evil and adulterous generation seeks after a sign, but no sign will be given it but the sign of Jonah the prophet.
