Matthew 12:36-40

King James Version

³⁶ But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment.

³⁷ For by thy words thou shalt be justified, and by thy words thou shalt be condemned.

³⁸ Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee.

³⁹ But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:

⁴⁰ For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.
