Matthew 12:38-40

21st Century King James Version

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 Jonah.

⁴⁰ For as Jonah 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.
