On the cross, Jesus saw the Temple and the priests slaughtering the daily sacrificial lamb, the Tamid. This lamb was offered twice a day, at 9am and 3pm, the hour at which Jesus was crucified and the hour Jesus died. During these two hours of sacrifice Jewish tradition states that special prayers, the 18 benedictions were offered – including prayers for redemption, forgiveness of sins, the coming Messiah, the resurrection of the dead. As the prayed, the two lambs were offered, Jesus saw and understood.
