Mat 12:38-39 Then some of the scribes and Pharisees answered, saying, “Teacher, we wish to see a sign from You. But He answering, said to them, “A wicked and adulterous generation seeks after a sign, and no sign shall be given to it except the sign of the prophet Yonah.
Signs do not produce belief. Signs confirm belief (Mark 16-18).
40 For as Yonah was three days and three nights in the stomach of the great fish, so shall the Son of Adam be three days and three nights in the heart of the earth.”
The roman “holy week / Good Friday” scenario does not pass the calendar, mathematics or Scriptural litmus tests. Messiah observed a “living” Passover with HIS followers on 14 Abib, the 3rd day of the week. HE was impaled the following day, 15 Abib, the 4th of the week. That night was night 1. The following day, 16 Abib is day 1. That night is night 2. The following day, 17 Abib is day 2. That night is night 3. The following day was the weekly Sabbath, 18 Abib is day 3. Yahusha rose from the grave on the 3rd day before night 4, just as HE had said. HE was seen by those coming to tomb as the Sabbath came to an end at the dawning of the next day or (1st day) 19 Abib. HE had risen prior to this time.
