The tombs were opened (ta mnhmeia anewicqhsan). First aorist passive indicative (double augment). The splitting of the rocks by the earthquake and the opening of tombs can be due to the earthquake. But the raising of the bodies of the dead after the resurrection of Jesus which appeared to many in the holy city puzzles many today who admit the actual bodily resurrection of Jesus. Some would brand all these portents as legends since they appear in Matthew alone. Others would say that "after his resurrection" should read "after their resurrection," but that would make it conflict with Paul's description of Christ as the first fruits of them that sleep ( 1 Corinthians 15:20 ). Some say that Jesus released these spirits after his descent into Hades. So it goes. We come back to miracles connected with the birth of Jesus, God's Son coming into the world. If we grant the possibility of such manifestations of God's power, there is little to disturb one here in the story of the death of God's Son.
