I did a little research and the Talmud was first written about 200 AD. Prior to that there was a long oral history of the OT. I have to assume that the Pharisees in the time of Jesus studied the OT so they should have known that He was the fulfillment of the OT prophecies. As for the modern day conservative Jews they study the Talmud. Talmud in Hebrew mens learning. Why they do not actually study the OT scripture is a mystery to me? They kind of sound like Catholics who are schooled in the church catechism, but never actually study the NT. I was raised Catholic and occasionally they would throw in a few Bible verses to sound legitimate every now and then. So glad I'm out of that bondage. As we know the week of Jacob's trouble is for the Jews to bring them to the knowledge of the true Savior!
