Justin Martyr, a second-century Father and apologist, recalls in his Dialogue with Trypho the Lord’s answer to those who asked for a sign. He says that, spoken obscurely, it was to be understood as a promise of rising on the third day after the crucifixion. It bears on the literal sense of the sign.
And that He would rise again on the third day after the crucifixion, it is written in the memoirs that some of your nation, questioning Him, said, ‘Show us a sign;’ and He replied to them, ‘An evil and adulterous generation seeketh after a sign; and no sign shall be given them, save the sign of Jonah.’ And since He spoke this obscurely, it was to be understood by the audience that after His crucifixion He should rise again on the third day.
