Your shallow understanding is caused by your lack of study in the Messiah. The Passover meal was where Jesus broke the bread (and no bones of Him were broken on the cross) and passed the cup of wine then said He would not drink it again until He comes into His Kingdom. If you have read this far, then you are in good shape, because I'm gonna recommend a book for your spiritual enjoyment. No really, it is a most enjoyable read, about the Feats of Israel and how they speak of Jesus and how they give prophecy of Him. The book is 'Unlocking The Secrets of The Feasts' by Michael Norten. The book is written/directed by Judaism scholars who are Christians. If you love Jesus Christ the book will regale your soul. You will read astonishingly beautiful prefigurings of Jesus. Here's a short paraphrase of just one morsel.
The Shepards who came to Bethlehem when Jesus was in the manger, after an Angel told them to seek him there, were actually more than common shepards. They were in a tower which gave them an excellent view of the baby lambs being born, so they could fetch the ones without spot or blemish, wrap a few strips of cloth around them so they were preserved for the sacrifice of Passover and Atonement. When the Angel told them they would find the child lying in a manger wrapped in swaddling cloth, the shepards knew this was a special child because they would place the special wrapped lambs 'up' in a manger to prevent them becoming blemished!

Since Mary and Joseph were the only people present at the nativity, just who narrated this story and to whom was it narrated???
A tower so they could watch lambs being born........uh, I guess it's possible....probable????no, but possible I guess.
