Then certain of the scribes and Pharisees answered him, saying, Teacher, we would see a sign from thee.
But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given it but the sign of Jonah the prophet:
for as Jonah was three days and three nights in the belly of the whale; so shall the Son of man be three days and three nights in the heart of the earth.
And others, trying (him), sought of him a sign from heaven.
And when the multitudes were gathering together unto him, he began to say, This generation is an evil generation: it seeketh after a sign; and there shall no sign be given to it but the sign of Jonah.
They said therefore unto him, What then doest thou for a sign, that we may see, and believe thee? what workest thou?
