Rabanus Maurus
Catena Aurea · Matthäusevangelium 12
Then certain of the Scribes and of the Pharisees answered, saying, Master, 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 to it, but the sign of the prophet Jonas: 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.
Then He begins to answer them, giving them a sign not from heaven, which they were unworthy to see, but giving it them from the deep beneath. But to His own disciples He gave a sign from heaven, to whom He shewed the glory of His blessed eternity both in a figure on the mount, and after in verity when He was taken up into heaven. Wherefore it follows, And there shall no sign he given it, but the sign of the Prophet Jonas.
