quotes from Chapter 2 Jewish Traditions of Prayer by Dr. Jan Verbruggen
"Especially after the destruction of the second temple and the explsion of the Jewish people from Jerusalem (70 A.D.) and Judea (135 A.D.), did the prayers come to replace the normal three daily sacrifices of the temple.""After the destruction of the temple, the synagogue service was called avodah, just as the sacrificial service had been called avodah."
