Input: Read this: There are several details that are only found in one of the gospel accounts. For instance, only Matthew's gospel mentions an earthquake, resurrected saints who went to the city and that Roman soldiers were assigned to guard the tomb, while Mark is the only one to state the actual time of the crucifixion (the third hour, or 9 am) and the centurion's report of Jesus' death. The Gospel of Luke's unique contributions to the narrative include Jesus' words to the women who were mourning, one criminal's rebuke of the other, the reaction of the multitudes who left "beating their breasts", and the women preparing spices and ointments before resting on the Sabbath. John is also the only one to refer to the request that the legs be broken and the soldier's subsequent piercing of Jesus' side (as fulfillment of Old Testament prophecy), as well as that Nicodemus assisted Joseph with burial.
Question: What did the Roman soldiers do to celebrate their victory?
