The early followers of Yeshua maintained a reverence for the Temple and its ceremonies right up until its destruction. The Twelve made it their regular meeting place for both worship and official business.
The Apostles were held in such high esteem by the Jewish people that their time of worship and consultation at the Temple was entirely respected. Petitioners and detractors alike left them alone in that holy place. Even the priests and Sadducees hesitated to interfere.
