Matthew 12:38-40 Then some of the scribes and Pharisees answered Him saying, "Teacher, we want to see a sign from you."

CLV⁽ⁱ⁾ ³⁸ Then some of the scribes and Pharisees answered Him saying, "Teacher, we want to see a sign from you." ³⁹ Yet He, answering, said to them, "A generation, wicked and an adulteress, for a sign is seeking, and a sign will not be given to it except the sign of Jonah the prophet." ⁴⁰ For even as Jonah was in the bowel of the sea monster three days and three nights, thus will the Son of Mankind be in the heart of the earth three days and three nights."
