Even modern Christian scholars readily admit that although the Jesus event did take place, the way in which it was recorded and later changed over time is less than reliable. Jeconias was his grandson, Jehoiakim being omitted. There is no such Messianic prophecy anywhere in the Old Testament prophets. Bethphage is not on the Mount of Olives but, in fact, a few miles outside of Jerusalem. And they called for Barabbas.
Scholars seriously question whether it even occured then.
