This passage is about the resurrection of Jesus Christ from the dead, and a plot to cover it up (Matthew 28:1-15).
Early in the morning, after the Sabbath, Mary Magdalene and the other Mary (see 27:56) came to see the tomb. They saw that the stone had been rolled away (Mark 16:4). Earlier, there had been a great earthquake, and an angel of the Lord came and rolled back the stone from the door and sat upon it. The guards shook for fear of him and became like dead men. When the women arrived, the angel told them that Christ had risen, and they went into the tomb and saw where Jesus had lain. The angel instructed them to go tell Jesus’ disciples that He had risen and would meet them in Galilee. As they went, Jesus appeared to them, and they worshiped Him. Jesus also told them to tell His disciples to go to Galilee where they would see Him.
While the women were going to tell the disciples, some of the guard came and reported to the chief priests what had happened at the tomb. After consulting with the elders, they bribed the guards with a large sum of money to say that the disciples of Jesus came at night and stole His body. Matthew concluded this passage of Scripture by indicating that this explanation of the empty tomb of Jesus was still being reported at the time he wrote his Gospel.
