Jewish scholars were so stunned with the arrival of Jesus and the miracles He performed that they debated for centuries over whether there were two Messiahs, as a suffering Messiah (Jesus read the passage from Isa 61 to them and stopped before the conquering Messiah is detailed) from the line of Joseph and a conquering Messiah from the line of David.
The same Messiah, Jesus, is fulfilling both roles. But the seventieth week of Daniel, as plainly written in Daniel 9 begins with a contract entered into with Israel, for seven years of Peace and Safety.
The sixty-ninth week ended when Jesus allowed Himself to be ushered into Jerusalem as King, the only time He did so during His first coming to the Earth. The calculation is so precise for the period from the command to rebuild Jerusalem to the entry into Jerusalem that for centuries 'scholars' claimed Daniel had to have been written after Jesus came and was crucified. Even the Book of Daniel itself was doubted by 'scholars', until a clay tablet was found in the base of a tower being excavated in Babylon which named The King and his son, Belshazzar, as dedicating the tower construction. And as you know, Belshazzar was the king in Babylon city when the hand writing on the wall occurred and Babylon fell to the encircling enemy armies.
Perhaps that is why the verse of the Bible says..”They will gaze upon him who was pierced and mourn...” There will be realization that the conquering messiah and the suffering messiah were the same person....
